Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent the runaway of a speed control system in a seek operation for the purpose of recovery of a track following operation without using a light beam moving direction detecting means. SOLUTION: A light beam spot is positioned in an objective track on an optical disk 1 by driving an optical head 4 with a positioning means 3. At this time, a track following control loop, a speed control loop and a means of impressing fixed acceleration by a kick pulse 34 are changed by a control loop changeover means 9, so as to perform each individual operation of the track following operation, the seek operation or the kick pulse impressing operation.  When an off-track state is detected by an off-track detecting means 8 during the track following operation, a controller 10 is so operated that at the time of performing the seek operation for the purpose of the recovery of the track following operation by making a changeover to the speed control loop, the control loop is changed once to the kick pulse 34 immediately before performing this speed control, and the positioning means 3 is moved at prescribed acceleration in an arbitrary direction for a prescribed period of time.

Abstract: PURPOSE:To change a floating stationary position of a friction plate, which is partly constituted of at least a magnetic substance and a permanent magnet or a superconductor, so as to simplify a structure by changing magnetic field distribution in a cylindrical superconductor through application of an external magnetic field and partial heating. CONSTITUTION:A cylindrical superconductor 1 is placed in a refrigerant vessel 2 filled with liquid nitrogen. When a magnetic field, having a peak in a part A, is generated by energizing an electromagnetic coil 3 in a region A, a friction plate 8, which is a magnetic substance, is closely attached to a flywheel 7 to transmit driving force because the friction plate 8 is moved to a position of the magnetic field most intensified in a contactless condition. Here, energization of the electromagnetic coil can be stopped because a residual magnetic field is provided in the superconductor. In the case of cutting off the driving force, a magnetic field is applied by first energizing an electromagnetic coil 4 in a region B. Next, a heating heater 5 in the region A is energized to break a superconductive condition in this part. Then the driving force is not transmitted by moving the friction plate 8 to a direction of the region B.
