Title: Seek circuit for optical disk
Inventor: WACHI SHIGEAKI
IPC: G11B7/085
Filed: 1989-08-29
Abstract: PURPOSE:To attain high speed seek operation without provision of a speed sensor by driving a means displacing an optical pickup in the radial direction of an optical disk in response to the difference between a current track address and a reference value. CONSTITUTION:A reference value changing time wise is formed between a current address AP and an address AT of an object track. The reference value is formed by integrating the speed change of an actuator 13 required for high speed seek operation. The difference between the reference value and the current address representing the position of the actuator is used as a drive signal of the actuator 13, then the actuator 13 is displaced in following to the reference value and the reference value corresponds to the speed information. Thus, it is not required to provide the speed sensor.

Filed: 1990-08-24
Abstract: PURPOSE:To restrain excessive rotating displacement of an armature block even when a platen gap is larger than a proper value so as to prevent breakdowns of an outer spring, inner spring and piezoelectric device by providing a small gap between an attached plate spring and an upper face of an outer block. CONSTITUTION:A plate spring 3a whose end is fixed to a side face in the direction of a tip of a wire 1 of an armature block 3 is extended in the direction opposite to an armature 2. When it is in a static state, a bottom face of the plate spring 3a is in parallel with an upper face of an outer block 6 having a small gap. Therefore, even if a platen gap x is set to a value larger than a displacement quantity corresponding to an extension of a piezoelectric device 8 generated by an impression of voltage, the plate spring 3a contacts with the outer block 6 from its tip gradually so as to bend due to the rotation of the armature block 3. As a result, displacement of each member is restrained and the bending stresses of an outer spring 4 and an inner spring 5 and the tensile stress to be generated at the piezoelectric device 8 will be not excessive so that breakdowns thereof can be prevented.
