Sir. Is this bias is used in eraseing process only.? Is it not used in recording. ? Expert like you. Sir said that. Magnetic. Recording is is a mixed result of bias. AC. Signal. And coming. Sound signal. 🙏
Also, on schematics, there is a conection from bias oscillator to recording amplifier. Why is it so? Shouldnt the bias benfonnected justo to erasing head?
Hi , I have made the same circuit and code but without a buzzer , and it don t work , is something what must be installed in Thonny or to set up this sensor ?,
Thank you for making such an wonderful video .👌 would you plz make a single transistor based head playback circuit which was found in old china made walkman (based on a single s9014 trasistor ) . if possible plz provide the circuit diagram of the same..
Ok So I built your circuit identically and my measurements are as follows: 5V: 47.54kHz, 14.40V PP 12V: 48.00kHz, 34.40V PP 15V: 48.60kHz, 41.20V PP My Erase head is from a Sony WM-D6C and measures as 0.9uh, 3 Ohms, I would be keen to hear what your is. I will try some different ones in the future. I want to build a 100kHz version with 45V PP, will see how I go with modifying this circuit... thanks!
