Abstract: PURPOSE:To use a material which will not become crystal as a recording medium and to obtain an optical disk suitable to said medium by giving to the recording medium at least two types of crystal structures in the solid state, holding the crystal structure inherent to one temperature area in the other one, and/or forming the medium with metal or alloy causing different volume changes in the crystal state. CONSTITUTION:The optical disk device 1 has a laser source system 10 generating laser beam having more than two wavelengths. A disk 40 supported by a disk supporting system 50 is irradiated through a beam splitter 20 to record, erase or read recorded contents on a disk, and a detector 30 reproduces a signal. In this case the recording medium has at least two types of crystal structures in the solid state, holds the crystal structure inherent to one temperature area in the other one, and/or composed of the metal or alloy causing different volume changes. Then the wavelength of the optical beam is selected at the time of irradiating the erasure optical beam so that the optical reflectance from said metal or alloy can be larger.

Title: Polygon scanner driving device and its manufacture
Inventor: KASHIMA WATARU
IPC: F16C17/10
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To reduce the deformation caused by the distortion of the polygon mirror while it is rotated at a high speed by fitting the flange member of the rotating side to the mounting hole of the polygon mirror and then, joining the mirror and the member through a plasticification deformation at the fitting part. SOLUTION: A polygon mirror 13 is pressed against a positioning surface 12d of a flange member 12 and fixed to a plasticifically deformed calking section. Since a projecting part 12c of the member 12 is plasticifically deformed, the joining is performed at the portion which is closer to the center (i.e., farther than the case of conducting a conventional screw tightening). Therefore, even though the inner peripheral section of a mounting hole 13a of the mirror 13 is slightly deformed, the deformation is relatively difficult to be transmitted to an opposite surface 13r. Moreover, even though the inner peripheral section of the hole 13a of the mirror 13 is slightly deformed to a larger size, the deformation is absorbed by a distortion absorbing groove 13b, the deformation of the outer side of the groove 13b is prevented and the distortion of the reflecting surface is prevented.
