Title: Magnetic disc control apparatus with parallel data transfer between disccontrol unit and encoder circuit

Abstract: A data processing method of recording data on a recording medium mounted onan information recording apparatus. The data processing method includesthe steps of dividing, in a disk controller, parallel data constituted byp bits transferred from a high-rank device into data each having q bits,where p and q are numbers; transferring the data each having q bits fromthe disk controller to an encoder as parallel data constituted by q bits;encoding, in the encoder, the data each having q bits to generaterecording signals corresponding to data to be recorded; and recording therecording signals on the recording medium, thereby recording the data tobe recorded on the recording medium. The data processing method mayfurther include the steps of reproducing, from the recording medium, therecording signals recorded on the recording medium; decoding, in adecoder, the reproduced recorded signals to generate data each having pbits; transferring the data each having p bits from the decoder to thedisk controller as parallel data constituted by p bits; and converting, inthe disk controller, the data each having p bits into parallel dataconstituted by m bits to be transferred to the high-rank device, where mis a number.
