Patent JP-H04339325-A (JP)
Title: Optical disk memory device
Inventor: NOMURA HIROO
IPC: G02B7/18
Filed: 1991-05-16
Abstract: PURPOSE:To reduce the cost of the device by reflecting the light from a stationary optical system toward a disk side, finely moving it in a focusing direction and providing a finely and roughly movable parabolic mirror in the radial direction of the disk. CONSTITUTION:A laser beam changed in direction by a galvanomirror is passed to a parabolic mirror 18 via a afocal lens 16 and a correcting lens 17. The parbolic mirror 18 changes the light path of the laser beam in the direction of a disk recording surface at 90 degrees, and at the same time, stops down the light. At this time, the afocal lens 16 greatly lifts up only the inclination of an optical axis on the parabolic mirror while suppressing the large deviation of the tip of light flux from a head with long light path whose light path was changed by the galvanomirror 15. That is, the spot position of the light can be changed and a tracking operation can be conducted while minimizing the eclipse of the light. Thus, the conventional functions of a lifting prism and an objective lens can be substituted by a single parabolic mirror and the cost of the device can be reduced.

Filed: 1985-05-23
Abstract: PURPOSE:To enable manufacture with a greater corrosion resistance and a greater strength and at a high accuracy, by building up a pressure-receiving plate of a diaphragm by plating and a peripheral anchor section by etching of a metal substrate. CONSTITUTION:A sufficient surface processing is applied to a metal substrate 16 having a smooth surface and after one surface thereof is covered with a masking tape or the like, a plated layer 15 is formed on the other surface thereof. Then, a photoresist 17 is applied on the surface opposite to the plated layer 15 to be patternized and an etching is done. By this processing, the portion without a coat of the photoresist 17 is melted away from the metal substrate 16, leaving that 16a with the plated layer 15 and a coat of the photoresist 17. As a result, the metal substrate 16a supporting the plated layer 15 is obtained with the photoresist 17 melted away. Thus, the plated layer 15 serves as a pressure receiving plate 11 while the metal substrate 16a serves as a peripheral anchor 12 to form a diaphragm 10.
