Filed: 1986-01-31
Abstract: PURPOSE:To improve the equal velocity property of a scanning surface without electric correction by forming respective mirror surfaces of a rotary polygonal mirror so that specific conditions are satisfied, forming transparent layers for correction on respective mirror surfaces and then forming a reflection preventing layer on the whole surfaces of the transparent layers. CONSTITUTION:The titled light deflecting system has the rotary polygonal mirror 10 and a rotating means for rotating the polygonal mirror 10. The rotating means consists of a motor or a proper rotating mechanism including a motor. Respective mirror surfaces of the polygonal mirror 10B are cylindrical surfaces or spherical surfaces. The radius R of curvature is determined so as to satisfy the relation of the shown equation I when the radius of the inscribing circle of the polygonal mirror 10 is A, the rotational angle of the polygonal mirror 10 is alpha and the deflecting angle of a deflecting light beam is 2theta. The transparent layers 10A for correction are formed on respective mirror surfaces 10B and the reflection preventing film is formed on the whole surfaces of the transparent layers. Said constitution makes it possible to attain approximate equal velocity optical scanning on the scanning surface without using an ftheta lens.

Title: Two-dimensional driving device of object lens
Inventor: YOMO MAKOTO
IPC: G11B7/09
Filed: 1984-02-09
Abstract: PURPOSE:To obtain a two-dimensional driving device of an object lens which stabilizes tracking servo in case reproducing by connecting a relaying member to a detainable detaining member and a device body through a shape memory element. CONSTITUTION:A coil spring 24 made of a shape memory alloy is heated at a temperature for the mother phase state, and the coil spring 24 is allowed to memorize the shape when the overall length is slightly shorter than that for recording. In case of a normal tracking operation, the coil spring 24 inflicts no influence upon an actuator 20 at all by a compression coil spring 25. When the coil spring 24 is heated by power supply at a recording time, the shape memory alloy is contracted against the force of the compression coil spring 25 to pull a relaying plate 7' through a detaining member 23. Since the relaying plate 7' is fixed to a base material by flat springs 5 and 6, it is balanced in a prescribed position and is set to the fixed state. As the result, the pitch of recording tracks is made uniform even if information is recorded on a disc having no pregroups, and tracking servo for reproducing is stabilized.
