Title: Control method for optical disk device
Inventor: GOMI AKIHIRO
IPC: G11B7/00
Filed: 1988-07-23
Abstract: PURPOSE:To prevent control to be instable or failed with an erroneous speed signal by monitoring the change quantity of a speed error signal, regarding the speed signal as the erroneous signal when a ceratin condition is satisfied and holding a former value. CONSTITUTION:A target speed generating means 2 receives a signal from an optical head 1 and counts the number of tracks to be passed. Then, a target speed is read from a storing means 8 and after that, outputted to a speed error detecting means 4. A speed detecting means 3 measures a time, which is needed to pass one track. Then, a speed to correspond to the measured necessary time and outputted to the means 4. Difference between the target speed and detected speed is obtained by the means 4 and outputted as a speed error. A speed error comparing means 7 compares this speed error with the value of the preceding two speed error to be stored in the means 8. When it is judged that the change quantity satisfies the prescribed condition, the value is judged as an erroneous value. Then, the value of the preceding speed error to be stored in the means 8 is read and outputted to a driving amplifier 5 as the value of the present speed error.
