Improved floppy disk data separator

摘要: A data separator for providing and clock information derived from a floppy disk to controller includes synthetic oscillator phase- locked loop which adjusts the phase of clock, thereby tend position inputs within central portion their associated half-bit slots. The center frequency may be modified 30 in accordance with prior adjustments compensate variations speed drive. Each slot is divided into "slices" are normally eight number, except that lengthened or shortened by one two centre pulses therein.
