ABSTRACT:
A method of and a system for efficiently using split information stored in an unnecessary data sector, thereby reducing unnecessary data. The system includes first registers respectively adapted to store MCDR values in response to a write control signal generated from a central processing unit; second registers respectively coupled to the first registers, each second register down-loading the MCDR value from the corresponding first register in response to a servo sector interrupt application signal inverted by an inverter, thereby generating signals indicative of an internal flag, an internal CDR value and a split sector number; a multiplexer adapted to multiplex the internal flag signals from the second registers, thereby generating a flag signal; a counter adapted to count the servo sector interrupt application signal, thereby generating a current sector number signal indicative of the number of a sector being currently accessed; a synthesizer adapted to generate a CDR signal based on the split sector number signal from each second register; and a comparator for comparing the split sector number signal from each second register with the current sector number signal from the counter, thereby generating a sector good signal.
