デイスク・コントローラ。 In a disk controller that writes data to or reads data from a disk,
A read-only file that stores parameter set information for multiple disk startup units and advance amount parameter set information for multiple buffer memories.
A memory circuit, a random access memory circuit in which the parameter set information is set, an electrically changeable read-only memory circuit that always stores the optimum parameter set information, and a memory circuit that actually operates the disk. A disk controller consists of a control circuit that controls the operation of the disk, and a microprocessor that controls the activation of the disk and the storage operation in the buffer memory.
