|5826093||Dual function disk drive integrated circuit for master mode and slave mode operations|
A single integrated circuit includes an on-board processor, a peripheral port, and a general purpose input/output (I/O) circuit that support both master mode and slave mode operations. In a master mode of operation, the integrated circuit functions as a d...
|5640538||Programmable timing mark sequencer for a disk drive|
A programmable timing mark sequencer automatically analyzes a sequence of data bits on a data input line. If the appropriate timing pattern is detected in the sequence of data bits, the timing mark sequencer drives a signal active on a servo timing mark o...
|5640583||Programmable servo burst decoder|
A disk drive controller integrated circuit includes a programmable servo burst decoder that can process any one of a plurality of servo sectors. A disk drive head reads each embedded servo sector on the disk and provides an analog signal, a servo burst, r...
|4746997||Method and apparatus for generating/detecting and address mark|
An address mark whose pattern is distinguishable from information data is produced by generating a number of relatively long pulses followed by a number of relatively shorter pulses. Preferably, a binary "1" is recirculated through a first predetermined n...
