摘要： On the occasion of stopping the tape being run at a high speed, a winding radius of the tape supply reel is detected, and a tape deceleration rate is set in response to the detected winding radius. After the tape running speed is decelerated in the deceleration rate up to a preset speed, VL, at which the tape being run can be stopped without damage, the tape is stopped by a brake means. Thereby, the tape can be driven at a higher speed than the speed, VL, without damage, enabling a reduction of time required for a fast forward/rewind operation.

摘要： On the occasion of stopping the tape running at a high speed, a winding radius of the tape supply reel is detected to set the tape deceleration rate (a) on the basis of the detected winding radius of the supply reel. After the tape running speed is decelerated up to the allowable speed VL in the predetermined deceleration rate (a), the tape is stopped by effectuating the brake. Thereby, the tape can be driven at the speed higher than the allowable speed VL without generating any damage, enabling reduction of time required for the fast-forward/rewind operation. This can improve application flexibility by providing a couple of tape running modes at the first high speed V1 which is higher than the allowable speed VL and the second high speed V2 which is lower than the allowable speed VL. In addition, running of the tape can be ceased within the predetermined time t from the input of the stop command signal by specifying the maximum speed Vmax depending on the preset deceleration rate (a) and limiting the tape running speed with the maximum speed Vmax.

摘要： A focus jump technique enables focus control on recording layers of a disc in such a manner that its effect is not absorbed by disturbance or a variation in the movement speed of an objective lens. The technique involves monitoring level of a focus error signal and rejecting noise from the error signal. A speed sensor detects movement speed of an objective lens; and a speed control circuit generates a voltage for controlling the objective lens, based on the detected movement speed. Movement speed of the objective lens is detected during focus jump, a corresponding lens drive signal is generated, and an end position is determined from behavior of the error signal immediately before the end of the jump. A focus control is pulled, from a focus point corresponding to one recording layer, into a focus point corresponding to another recording layer forcibly in a stable manner.

摘要： During a normal operation, a tracking control signal from a tracking controller is supplied to an adder via a first switch and to a radial deviation component detector. The radial deviation component detector determines a radial deviation component EC of AC caused by radial deviation of an optical disk from the tracking control signal and supplied that component to the adder via another switch. For a track jump, the first switch is turned OFF, cutting off the tracking control signal. Thus, the radial deviation component EC and a jump pulse signal from a jump signal generator are added together by the adder. However, an offset of the tracking control signal TC detected by a DC component detector is further added. To avoid instability, the track jump is compensated so as to be normally carried out even if a DC offset is added to a tracking control signal.

摘要： An IC provided in an optical disk device having an objective lens and a pickup for a disk. The IC has a circuit for holding a signal which drives the objective lens in a focus or tracking direction and for detecting the moving direction of the objective lens, and a circuit for generating a signal which applies an acceleration to the objective lens. When the objective lens passes through a defect on the disk, on the basis of the detected moving direction of the objective lens, the IC applies the acceleration alternately in plus and minus directions to the objective lens to make the objective lens stationary. As a result, after the defect passage, the objective lens can be quickly returned to a focused point or an on-track position and reproducing/recording operation can be resumed.
