摘要： In a recording/reproducing apparatus, the controller has a function of increasing a count of incoming head move request pulses by one each time a head move request pulse is supplied while decreasing the count by one each time the magnetic head is moved over one data track by the magnetic head drive to provide a present count, and control the magnetic head drive to move the magnetic head at a speed based on the present count to a desired data track. Also, the magnetic head can also be moved over successive data tracks to a desired data track with a high accuracy.

摘要： Information signals recorded in a signal recording area of a magnetic disk 100 are reproduced for each sector unit by a magnetic head 3, and are taken out through an equalizer 8, an ECC circuit 9 and a buffer 10. A control circuit 12 obtains an estimate value indicating the difficulty of reproduction with respect to operation for reproducing the information signals from the magnetic disk 100, and accumulates the estimate value obtained until the information signals can be correctly reproduced. When the accumulated estimate value has become a predetermined value or greater, the control circuit 12 carried out control to record the information recorded in the corresponding sector into another sector. Thus, generation of such a state that the information signals cannot be reproduced in the future can be prevented.

摘要： A disk device having access to a disk in different writing modes includes a host PC. The host PC sends a command including a data transfer rate to a controller (disk drive). When the command designating the data transfer rate is received, the writing mode employed for writing data to a disk is automatically switched. The host PC already has the transfer rate to be sent. It is unnecessary to newly prepare a special command to notify the controller in order for switching between the writing modes. Therefore, versatility will not be impaired.

摘要： In a servo area SA on a track that is empty of data and that lies outside a user data read/write area, to and from which a user data of a floppy disc is written and read, format information FI of the floppy disc is recorded. The format information FI is recorded along with a track number TN in a gray code area GA in the servo area SA. Thereby, the format of the floppy disc can be identified with no identification hole or the like formed in an envelope encasing the floppy disc.

摘要： A disk device for performing error-correction processing is loaded with a high-reliability disk to which a C1 code as a low-level error-correction code (ECC) is added for every sector, and a C2 code as a high-level ECC is added for every plurality of sectors. A host computer includes a device driver corresponding to the high-reliability disk. When data written to the high-reliability disk is read, low-level error-correction is performed based on the C1 code in units of one block corresponding to one sector, and the corrected data is notified to the host computer. Simultaneously, the C2 code along with the data for a plurality of blocks is loaded, and high-level error correction based on the C2 code is thereby performed.
