Title: Capstan motor control system
Inventor: UEDA HIRONORI
IPC: G11B15/46
Filed: 1989-10-27
Abstract: PURPOSE:To prevent the velocity of a capstan motor from being rapidly fluctuated by using phase difference data at the time of capstan motor control in a stable state when a control signal recorded to a control track is made irregular. CONSTITUTION:When it is decided by an error data deciding device 14 that the phase difference data are out of a reference data range, a switch 4 for changing over data is controlled so that the previously sampled phase error data in the reference data range can be inputted to a phase control computing element 5 as the phase error data to execute phase control arithmetic this time. When the phase error data are within the reference data range, these data are held in an error data holder and become data for motor control in case the phase error data of next sampling are out of the reference data range. Thus, when a reproducing control signal is instantaneously made irregular, the rapid velocity fluctuation can be suppressed.
