Abstract
An optical pick-up head is provided, which comprises a holding body used to hold the first transmitting element and the second transmitting element orthogonal with each other, mounted with a permanent magnet; and a base mounted with a iron core and a core which are used to hold a rotary shaft, and to switch or to hold the holding body in the first switching position and the second switching position, so that the deflection of the light axis generated by the light beam transmitting means used for the adjustment of the light power of the light beam is suppressed with such a simple mechanism. In the first switching position where the light beam passes through the first transmitting element, the small projections of the holding body is sucked and holded by the permanent magnet and the iron core with the posture of abutting with the limit face of the base, and in the second switching position where the light beam passes through the second transmitting element, the small projections of the holding body is sucked and holded by the permanent magnet and the iron core with the posture of abutting with the limit face of the base, so that positioning is made. The first and the second switching positions can be switched by the application of pulse on the coil.
