<p>PURPOSE:To make the parts used in common even in the case a tracking system is changed. CONSTITUTION:A general purpose prescaler 54 generating a reference pilot signal supplied to an ATFIC 2 is incorporated into an 1 chip microcomputer 1. At the time of recording, the pilot signal outputted from the general purpose prescaler 54 is supplied to a magnetic head 41 through a low-pass filter 61, adding device 45 and amplifier 46. At the time of reproducing, the reference pilot signal outputted from the general purpose prescaler 54 is supplied to a balance modulator 25 through the low-pass filter 61. A pilot signal reproduced by the magnetic head 41 is supplied to the balance modulator 25. By the balance modulator 25, cross-talk components with the adjacent tracks are produced from both input pilot signals.</p> |
