ABSTRACT:
A method and apparatus for effectively adjusting signal characteristics such that they can be used with incompatible recording formats. In particular, the method and apparatus may be used to adjust the ATF sampling pulse width externally to shorten the sampling time. An externally generated timing signal controls the switches connected in series with charge holding capacitors for shortening the sampling time of the ATF sampling pulse width generated by a servo chip, such as a Hitachi HD49228FS servo chip. In the latter part of the ATF sampling pulse, the externally generated control signal opens up the switches, thus inhibiting further charging into the capacitors.
