Abstract

PURPOSE: To oscillate the single semiconductor laser pickup toward the desired tracking direction, by supporting the semiconductor laser pickup in the ball yoke of magnetic circuit of the focus direction exclusive use driving part, through the use of the support member having almost double cylinder construction of inner and outer cylinders.
CONSTITUTION: The support member 2 has almost double cylinder construction where the inner cylinder 2A and the outer cylinder 2B are linked with the continuous piece 2C, and the semiconductor laser pickup 1 is inserted and supported in the guide hole 6a of the ball yoke 6 of the focus direction exclusive use driving part 3. When power is applied in the electromagnetic coil 8 of the focus direction exclusive use driving part 3, the semiconductor laser pickup 1 is oscillated toward focus direction to adjust the collection of the beam spot irradiated on the disc 15, and when power is applied to the electromagnetic coil 13 of the tracking direction exclusive use driving parts 10, 11, the semiconductor laser pickup 1 is shaken left and right by taking the inner cylinder 2A made of an elastic material as a fulcrum for the oscillation.
