Information recording/reproducing apparatus for executing system control and servo control by single CPU

Abstract

An information recording/reproducing apparatus includes a single arithmetic device for executing, in parallel, system processing for processing a command from a host computer and servo control processing for positioning a recording/reproducing head on a target track. The arithmetic device executes preparation processing for a recording and/or reproducing operation to be executed after a seek operation, during the seek operation of the head to the target track. The preparation processing includes a setting operation of a frequency of a synchronous signal used for recording and/or reproducing information, modulation processing of recording data, or the like.
