Title: Optical disk
Inventor: YOSHIMURA HIROSHI
IPC: G11B7/24027
Filed: 1986-08-29
Abstract: PURPOSE:To prevent the generation of cracks of an optical disk and to improve the reliability of the disk by forming guide grooves at the areas corresponding to the recording areas of a recording film with prescribed depth and a prescribed pitch and also forming a recessed/projection part having specific surface roughness at an area excluding the recording areas. CONSTITUTION:The guide grooves 6A1 and 6B1 are formed with prescribed depth and a prescribed pitch at parts 8A1 and 8B1 corresponding to the recording areas 3A1 and 3B1 of the recording films 3A and 3B formed on the single side of disk substrates 8A and 8B respectively. While the pregrooves 6A3 and 6B3 forming a recessed/projection part having 300-2,000Angstrom  surface roughness are provided at the parts 8A3 and 8B3 corresponding to the areas 3A3 and 3B3 excluding those recording areas. The films 3A and 3B having different heat expansion factors from those of substrates 8A and 8B are obtained owing to the presence of said recessed/projection part. As a result, the produced internal stress is reduced over the entire surfaces of both substrates 8A and 8B. Therefore, the internal strains of both substrates 8A and 8B are not increased to prevent the generation of cracks of an optical disk.

IPC: B66F7/28
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To maintain its surface almost in the same plane shape as a floor surface by downward moving a cover plate by compressing an elastic body by making its load act on the cover plate by lowering a receiving stand, and raising the cover plate by elongating the elastic body by removing the load acting on the cover plate by raising the receiving stand to the contrary.

Therefore, since a load placed on a cover plate 1 is removed, a compression coil spring of an elastic body 2 is elongatively deformed, and an upper holder and a lower holder become long in the vertical direction, and the cover plate 1 moves upward. In this case, in a condition where the reverse of the connecting beam L4 is positioned in a pit P2 for a beam, the cover plate 1 moves upward while being brought into pressure contact with the respective reverses, and slips out of the pit P2 for a beam, and after moving upward from this, elongative deformation of the upper holder, the lower holder and the compression coil spring is respectively checked by a stopper, and a surface of the cover plate 1 is maintained almost in the same plane shape as a floor surface.
