IPC: G11B21/08
Filed: 1990-04-03
Abstract: PURPOSE:To write a servo signal in a proper position by detecting the abutting position of a magnetic head and a stopper in a head disk assembly and correcting the data at a standard position set in advance toward respective tracks. CONSTITUTION:The magnetic head is moved by controlling a VCM driving mechanism 32 with the standard position in a memory 42 as a target in respect to the track set at the outer-most periphery of a magnetic disk. A voltage to be supplied to the driving mechanism 32 is monitored by a VCM voltage detector 44, and the movement distance of the head is measured by a laser range finder 36a. The abutting position of the stopper and the head is calculated by subtracting the returning amount of the head caused by the elasticity of the stopper which is measured in advance, from the measured distance of the range finder 36a when the supply voltage is rapidly increased to the peak. With this calculated position as the servo signal writing position of the track set at the outermost periphery, all the standard positions of the tracks in the memory 42 are corrected, and the servo signal is written in the position.

Filed: 1981-06-10
Abstract: PURPOSE:To check the occurrence of a hang-up state by providing a counter step advanced on the execution of every prescribed processing unit, and allowing each utilization source to read the value of the counter. CONSTITUTION:The control part 6 of a disk pack device 5 is provided with a counter 8 step-advanced on the execution of every prescribed processing unit, and while the CPU1 of a system A uses the disk pack device 5, a busy signal is sent back for access from the CPU of a system B.
