Abstract
A disk drive system is disclosed that includes a disk device coupled to control circuitry. The control circuitry encodes data using a modulo code. The control circuitry separates the data into blocks and encodes the data by inserting stuff bits between blocks according to the modulo code. The control circuitry converts the encoded data into a write signal and transfers the write signal to the disk device. The control circuitry also receives a read signal from the disk device and converts the read signal into a data signal. The data signal represents blocks of data separated by stuff bits. The control circuitry detects errors in a block of data by determining the modulo value of the block of data and the following stuff bits.
