Functions of play and record with a tape head. How to make a rudimentary tape head. A recording tape head can be used as a magnetometer or magnetoscope to detect magnetic fields. - Věda a technologie
A very romantic scene with heads getting close and music is playing ;)
WOW !! Its TRUE !!!
0:33 EHMMMMMMMOEOEOEOEOEMMMMMMMMGGGGGGGRRRRRRRRRRRRRR.....

Don’t forget about the rings
0:34 Hahaha. The noise goes from sounding like a car engine, an engine airplane. XD
I was gonna say my stupid neighbor is out there weedwhacking again!!!
Very good. Car 'cassette adaptors' work in the same way, and the results can be surprisingly good.
How would ya do that??
What you've got at the beginning is (IIRC) a very basic version of how old Hammond organs worked.
I have just seen.

Really interesting and amazing how the world has changed.
Thank you.
You've given me something to think about also - I've spent years and years piddling about with crystal radio, and I've now finally decided to start playing with tape. Got an ancient cassette deck (an ITT L 53 automatic) and after having had to repair (rebuild) it, i thought 'y'know, I could maybe do this from scratch' - so I've made some tape and and a head and plan on making up an amplifier/blah and having a go at actually making my own tape machine.
Yep, I have way too much time on my hands. But yeah, you've done an interesting video here :)
I was going to post the same, but also about the second method, if you only have a cassette in the car, you could buy what looks like a cassette that has a head inside, a wire coming from that cassette plugs into an mp3 player etc.
Absolutely fantastic video. Thanks!
That was a cool experiment. I'm looking for this video. now i am able to understand how so many bluetooth cassette videos were done. Thank you 🙏
Very interesting video! I actually have a better understanding of how tape player heads work now from watching this. Good work.
Thank you for the comment!
@@tinkerbit can I make it with ferrite cores or not and thanks this video was great 👍
now that's what I call an analog oscillator
SUCH A NICE EXPERIMENTAL VIDEO !
OUTSTANDING IDEA! SUPER KUDOS TO YOU MAN!
Great video. Thanks for sharing!
Love it, you're a genius!!
Cool! It just gave me an idea for an alternative REVERB effect!
Nice illustration, thank you for taking the Time.❤ ❤Making the understanding of induction a lot easier..
That's a cool experiment. Thanks for sharing.
Excellent. You are very ingenious
Thanks for a very interesting video !
Excellent explanation.
Best experiment on tape heads...❤️
The magnet on the motor was square (squareish).. would you get different tones if you used say a triangle shaped magnet?
Fantastic dude...👍👍👍
Great experiment.
Interresting mind blowing experiments.
Also my tape head won't make any noise. I've got it wired to a stereo system, how do I wire it?
very cool. thanks for the great ideas!
Thanks to you for commenting.
Muito interessante !
Have you tried using a ferrite core, the round ones used in power supply's.
What mixer is that?
Love it
Pretty cool!! I like it, simple, but very effective...by the way I have that same phone. Thanks!
Thinking that this is 1890 technology. Yes right. Someone made a telephone calls recorder with magnetic steel wire as cassette tape and thin silk covered wire coils as recording head back in late 1800. Cool, isn't it?
Yes. It's cool. At least then you could have an intuition of the workings of that magic. Now we have black boxes.
Excellent friend
I have an 8mm sound projector with a burned play head. Is it possible to open and repair it?
Excellent 😃
I would like to know if it is possible to record sound on a fishing line
Still my favorite youtube video
A strangely fascinating video
Can you use all playback heads for recording, if you feed them electricity?
Superb!
Do you just have an output soldered directly to the head?
thank you frend its help me :)
Is there a possibility for short circuiting and burning the phone's DAC while doing that if you happen to have too low impedance on the coil?
I was just about to comment something similar. Definitely wouldn't recommend doing that without knowing how to calculate impedance and containing proper tools if you plan on doing that regularly.
You most certainly can mess up your phone, computer, etc
Well most likely the bolts impedance is way higher than a speakers so i dont think that will do anything. Plus heaphone jacks are ac coupled so i doubt it will get damaged for something less than 4 ohms
This is awesome, did you by any chance get any audio samples?
No. Only what is on the video.
just amazing
thank you
Thank you too!.
I would like to know if I can record sound on a steel string like Valdemar Poulsen's invention
Verry Cool,
I have a project I like to ask You few questions. How I can contact You.
Thank You
Behringer Eurorack, cant remember the model, I dont have it at home now. I use it only as a pre amplifier for this clip.
Dude, you are awesome
+David Refoua Thxs.
Thanks for uploading. Tried this, but getting very low volume. I have also tried soldering the tape head to guitar lead and playing through guitar amp to see if it will improve volume but still struggling to hear. Any tips? could it be just bad quality tape heads? thanks again
+Ian Tully Perhaps, but there are many factors: impedance matching the most important I think.
this is pretty cool.
That's cool....more pleeeeeeese
newbie question: how is the self-made tape head not short circuiting? shouldn’t there be some sort of resistor involved?
Genio!!!!!
Is your tape head just soldered to an amp? what wattage
Great!
man that´s wireless broadcast!!! ...cool work....
You're so smart!
REALLY, R.E.A.L.L.Y INTERESTING
👍😎
Nice! :)
can you record a cassette with this 1:35?
Thanks
Hey, I figured you or someone here might know about this. So basically a tape head can be used to both record and play, right? If I have a cassette player that does not have a record function, would it be possible to make it record? How complicated would it be or is it just a matter of inputting a signal to the tape head?
+Pentti Housu First you need to delete the previous record. That can be done with a permanent magnet or record to a new tape once. If you don't delete, you get a "mixed" recording. The second thing is that you need to invert the circuit. In a player the amplifier has the head in the input and the speaker at the output. In recording mode, the input is the microphone (or radio in a radiocasette) and the output is at the head. It is really complex. And this is only to get a bad recording. Recorders have circuits with frequencies to control byass and many aspects as impedances, noise, etc.
^ yes applying the right bias would be difficult to get a good recording
Какие контакры с гооловки подключать?
Don't you need an amp for the head? You just put it straight in the mixer? Wich cables/colours from the head did you make to an tele contact? I have four or five cables with different colours from the heads I've been taking out from normal cassettplayers. I guess there both record and play in ther same head? But I can't make it sound that good. I get VERY low and bad output signal
Same here! I don't know if its due to an old tone-head but I too get a really noise output signal. I would love to see/read a more detailed explanation of the experiment.
Besides that, I found it very inspiring.
@@madsfors try something like a step up xformer
does the metal object spinning need to be magnetic to me picked up by the tape head?
I think yes.
1:43 distilled essence of a cassette adapter. I was in my sister's husbands truck and were were listening to a cassette tape and the sound was coming and going and I asked him why it sounded like that and he didn't know what happened and I then asked him, "Did you put the tape near a magnet?" He said "I put it near a car speaker..." Then I told him the sound on the cassette is stored using magnetism and the speaker erased some of the signal by setting the selectively magnetized areas of the tape to the same poles. He thought it was a light or a touch (like a phonograph needle) or some other weird wizardy of something. Now he takes better of his tapes...
Have you ever resolderd new wire to a cassette head? I'm looking to replace old fraying cassette head wire thats kinked. Worried about heating the tape head as it will magnetizing the head. Any experience you could share.....?
No. But I think it is not as sensitive as a transistor. Heat the less possible but I think it will stand.
Thanks very much, I've ordered some new wire just waiting for the snail mail to come in.
i thought that heat will de-magnitize things
Nice vido
Bro pls help. I have a tape head with red white and ground, how do I connect these directly to a input jack?
I understand that red and white are right and left channels respectively and groung is common, back part of jack
Can you play tapes with that washer?
Super bro
What happens when i join those wires phone that earphone jack straight to the wires that go to the head and ommit the head all together, will I get sound!?
Just a typical day in the sennheiser workshop
mic core or voice coil is the example
So basically you reinvented the tonewheel. Now i wanna see someone build a hammond from tapeheads and DC motors.
+Guest Mann i see a video here, on youtube, of a guy who made it!!!
wow nice gob!!!
Thx!
the aux cable has 3 wires... how are you connecting the 3 wires into the 2 wire magnetic ring?
Should be L, R, and Gnd, so i'm guessing it was just R and Gnd.
Interesting stuff. Be good to use as a re-amping tool.
Thank you for the comment.
I got a mini jack to cassette adaptor, you know the ones for old car decks, just to try this out.
OK.
C est vraiment interesant
Tone generator XD
Alternate title: How to connect a phone to a mixing desk using first principles.
Get 6 of the tape heads and make an electric guitar pickup, should work theoretically, but I've made my own which isn't all that hard, so I've never tried these on a guitar or if I did I can't recall, old age, lol. Anyone up for giving it a go, pretty sure it will work.
Yes i know. Since i see you are interested in sound, can you make a video about wireless audio transmission?
I will try this experiment
But there are 2 coils in my recording tape head
Those work identically, the two coils are in parallel with a common lead. One coil is for reading/writing the left audio track, the other is for the right track. You can connect any two opposing wires and you'll get the same results as the video.
Ho!... Amazing
0:45. Woo! I want one!!! Gonna buy some severed mino 1/8” tape heads. Gonna take an r2r digital to analog converter. Add up the MSB all the way through the LSB. All of these time glitched square waves should be equal amplitude. Then chorus vibrato them with 30 different heads. So 30 vibrato nasty digital bit rate noise floors from the sample rate fold overs from each next amplitude modulated peak with positive and negative side bands that are pulse formed going through zero and back up to infinity hertz. So take this signal and put it through the Brado so that the vibrato now sounds like noise. But make sure that your course really really slow so that the D-tunes cycle goes like once every hundred seconds so like a very slow LFO first and then the faster and faster ones until about 20 Hz and they’re all going up and down in pitch between 1 Hz and 20 Hz. Maybe I could do it with a saw wave pulse width modulation comparator and series and get a pet sweep out a pulse width. But anyways the tape is really good way to do it so I need 30 tape machines with erase play back and record heads so that I get all these Roboto things the tea Rex replicator is way too expensive I have one of them and it sounds digital because the motor the motor is digitally controlled so I’m gonna have to replace that so I have one of the Brado but I need another vibrato vibrato. So I really like your video anyways I’m gonna make analog I mean digital sound analog because I’m gonna add in a really quiet noise floor that makes the Apple TV modulated digital noise floor I didn’t say Apple TV I said amplitude modulated that’s right anyways of course is in Illinois so then it’s just like having a nice noise floor and the only thing that can be wrong about digital is the bad noise floor and then plus that it got rid of the real magical mojo that’s more than somebody like me that can mess with. Just put it through analog vocoder and I’ll probably be good enough and then play certain sections that are only analog. But at least now you have a pretty good siding ha ha. Whatever I think you already know all this stuff anyways but I’m having fun doing it and I did not realize that you could do this with the tape pad so thanks for A thanks for the time warp
If you were to drag that washer with the magnetic wire across a tape from a cassette would it actually read it?
Yes.
mopatin cool how many loops did you have to get for that washer to work
sos Can't remember, but with 40 or 50 I think is enough.
The gape size needs to be less than lenght of wave on tape. For real cassette its some micrometers.
sos
Yeah in theory but read heads arent silk smooth for no reason. Plus you needs very small tolerances and stuff for it to work properly. Its simple bug its hard to achieve with home tools alone
An great idea to reuse that old car-radios only with radio and tape deck! :)
BTW, what's this music's name??
The song is "Getting there". You can find it at CZcams Audio Library. czcams.com/users/audiolibrary
mopatin Thanks!
Is it possible to use a cassette mp3 adapter head as a horrible record head?
To record something on the tape, you need to add an ultrasonic bias signal above the audio signal, because of nonlinearity of magnetic material (search "magnetic hysteresis loop"). The bias signal works somewhat like dithering and provides a nearly-linear mode of magnetization. I made some successful experiments of recording to the tape directly from PC soundcard just by soldering 3.5mm jack to the playing/recording head observing wiring. Basically, you just need to setup 48KHz mode and add 24khz sinusoidal tone (in Audacity, use Square because sinus at Nyquist frequency produces no signal), with amplitude -2dB max., and audio amplitude is -30dB max @ 1 KHz. Also, some equalization is needed because head distance produces Gaussian blur in the time domain, so mid and treble frequencies will be attenuated. Equalization curve is selected experimentally and looks like this:

It's like the Car Cassette adapters working
bro you should test reading and writing and make cheap storage devices ..or work along those lines
Awesome experiments, what's the name of the song?

1:58 this is how new tape heads are born
if I strap on my electric guitar and turn up the gain, then stand beside my record player playing a record but with the stereo amplifier turned off, and if I lean in so that the guitar pick-ups are close to the stylus riding in the groove, I can hear the record playing through my guitar amplifier.
Good.
bluegrassbarry Keyword is electromagnetic induction.A phenomena of phisics.Magnetic change induces electric current in wire coil.In your case the vibrating guitar string alteres the magnetism of your picup coils and that weak signal is amplified through your guitar amp.
Lenz's Law ?
neat
Thanks!
прям открытие пипец))
Kid of sad that i have discovered these things on my own and used a lot. I understood the tech with just one concept of electromagnetic induction in my head.
I still wonder how that tiny gap in the head (2..4 um) was made, what technology used? In '60s-'80s!
They were making exceptional quality for exceptional prize. Not like today when all can afford for the same final result. I was then thinking how to buy suiting me stereo cassette recorder for years.
Yees. When I was a child I told my father that if I were extremely rich I would buy anything and he told me that then nothing would exite me.
That is how they create cassette adapter
ha, kinda like a budget isolation audio transformer
