ABSTRACT:
A method of controlling a magnetic disk unit. The method controls the magnetic disk unit which comprises a disk enclosure part and a printed-circuit board part. The disk enclosure part includes at least one magnetic disk, at least one magnetic head and a mechanical part for driving each magnetic disk and each magnetic head. The printed-circuit board part includes a circuit part for controlling the disk enclosure part. The method includes the steps of writing on the magnetic disk version data indicating a type of disk enclosure part after the disk enclosure part and the printed-circuit board part are assembled, and automatically setting the circuit part of the printed-circuit board part depending on the version data which is read from the magnetic disk after the magnetic disk unit is completed.
