Abstract
Either one of recording or reproduction of data is effected by use of an information processing system that includes a recording/reproducing apparatus for effecting at least one of recording of data on or reproduction of data from a recording medium on which a plurality of tracks are provided, a controller for controlling the recording/reproducing apparatus and a host computer connected to the controller via a small computer interface. A partition command is sent from the host computer to the controller through the small computer interface so that the data tracks are divided into a plurality of logical partitions to designate the sector size to be used in each partition. The parameters for the partition division and the sector size are stored in the memory in the controller on the basis of the partition command signal sent from the host computer. A selection command for designating either one of the divided partitions is sent from the host computer to the controller via the small computer interface. The controller controls the information recording/reproducing apparatus so as to effect either one of recording of data on or reproduction of data from the data track in the partition designated by the selected command according to the parameters stored in the memory.
