Abstract:
A disk device, comprising:a recording medium having a recording surface including a data block and servo block thereon, said servo block having servo data recorded therein for controlling the position of a head, on said recording surface, which records and reproduces data in said data block; a signal processing device for detecting data in said data block from a signal read from said recording medium and for outputting said detected data via a first bus; a data processing device for controlling the position of the head on said recording surface, which records/reproduces data in said data block and for reading said reproduced data via said first bus in response to said servo data which is detected from the signal read out from said recording medium; and a processor for controlling said signal processing device and data processing device; said signal processing device including an analog-to-digital converter for analog-to-digitally converting a servo data signal read out from said head and selecting means for outputting to said first bus, said servo data which is detected from said read signal and converted by said analog-to-digital converter; said data processing device including means for holding said servo data which is input via said first bus, control information means for delivering timing for fetching said servo data which is delivered from said signal processing device to said data processing device via said first bus into said holding means of said data processing device, and means for outputting said stored servo data into said second bus.
