Abstract

PURPOSE:To clearly classify a magnetic disk drive different in the number of tracks to be controlled by seeking a head up to the track of a numeric value in which the maximum number of tracks can be controlled. Returning next, it to the suitable track and checking the signal of a track '0'. CONSTITUTION:When a standard 5-inch magnetic disk drive on a system and an 8-inch magnetic disk drive are loaded as an option and it is discriminated to which magnetic disk drive the drives are connected, a head is seeked up to the track of the numeric value in which the maximum number of tracks can be controlled out of the number of the tracks different in magnetic disk drive, returns up to the suitable track and the signal of a track '0' is checked. Thus, a checking signal can be relatively obtained and it can be clearly discrimi nated which magnetic disk drive is connected.
