Title: Servo system control method of hard disk drive
Inventor: KIN GAKUHIN
IPC: G11B27/36
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To ignore fault position information to prevent influence of disturbance on normal servo area for stable drive if a fault is found in the servo through the track seek. SOLUTION: A servo failure list is read from a disk 46 with a head 47 and it is then stored in RAM 44. Thereafter, whether there is a fault in the servo or not is checked with the track seek instruction of CPU 41. If there is a faulty servo is the fault list, the position information of this servo is ignored and the track position information is estimated from the position information of the servo before the relevant servo to perform a predetermined servo control algorithm. If there is no faulty servo in the fault list, the predetermined servo control algorithm is executed depending on the position information obtained by reading. Thereby, if fault in the servo area is less than the predetermined reference value is the fault detecting process in the manufacturing process, manufacturing process can be continued to shorten the manufacturing time.  During use, the fault position information is ignored to prevent influence of disturbance on the normal servo area to assure the stable drive.
