Abstract

PURPOSE: To vibrate a semiconductor laser pickup efficiently in a focus direction, tracking direction and tangential direction, by arranging driving mechanism parts around the pickup.
CONSTITUTION: Semiconductor laser pickup 1 is fitted in center hole 4b of support 4 at equal intervals from driving mechanism parts 2A, 2B, 2C, and 2D, and driven by driving coils 12 on the reverse surface of arm part 4a. When in-phase signals are supplied to all driving coils 12, it is applied with vertical force; for example, when in-phase signals are supplied to driving coils 2A and 2B and anti-phase signal to 2C and 2D, the pickup rotates on point 0 in the tracking direction and when in-phase signals are applied to 2A and 2D and anti-phase signal to 2B and 2C, it rotates on point 0 in the tangential direction.
