Patent number: 5197060Abstract: The present invention relates to a structure of optical disks fabricated by pasting two substrates together using an adhesive composed of thermo-setting resin and UV-curing resin and to a process for fabricating the said optical disks. Ceramic layers are formed in the inner and outer circumference parts but neither recording layer nor reflective layer is formed in the said parts so that UV-light can penetrate into the adhesive. Therefore, the two substrates can be temporarily fixed by irradiating them with UV-light because the UV-curing components of the adhesive in the inner and outer circumference parts hardens thereby. The optical disk temporarily fixed is heated to harden the thermo-setting components of the adhesive, thereby the substrates being perfectly pasted together. The temporal fixing of the substrates using UV-curing resin has such effects as that the substrates can be set upright, and therefore no strain occurs in the substrates, and that the adhesive does not overflow.Type: GrantFiled: September 11, 1990Date of Patent: March 23, 1993Assignee: Seiko Epson CorporationInventor: Masahiro Yatake

Patent number: 5195079Abstract: A disk driver in which a disk is inserted has a head (12), a holder (5), and a slider (14). The holder ascends and descends between a first position and a second position. The head ascends and descends between a third position and a fourth position in response to the ascending and descending of the holder. The disk (3) is inserted into or ejected from the holder (5) at the first position when the head (12) is at the third position, and information is recorded on or reproduced therefrom by the head at the fourth position when the holder is at the second position. Since the third position is higher than the first position so that the head does not hit the inserted disk, there is a space between the first and third positions. Accordingly, the slider (14) is located in the space so that it can avoid hitting the head, and thus the disk driver can be made thin.Type: GrantFiled: June 18, 1991Date of Patent: March 16, 1993Assignee: TEAC CorporationInventors: Kazuhiko Inoue, Takashi Watanabe, Yoshio Hirose

Patent number: 5182735Abstract: A magneto-optic playback apparatus which plays back information from a recording layer (RL) which exhibits different light absorption of left and right circular polarized beams emitted from a laser (L). The laser (L) operates in two different polarization modes, DE and TM. Polarization converter (PC) converts linear polarized radiation from the laser in one plane to one circular polarization orientation (left or right) in one direction of transmission, and then converts the opposite circular polarized radiation orientation back to linear polarization in the other direction of transmission. The laser switches between modes according to the magnetic orientation of the medium which is determined by the reflected light. Loss control element (LC) selectively increases the TE losses in the extended laser cavity. The self-coupling laser's operation in either the TE or TM mode depends on the differential absorption by the media of right (RCP) or left (LCP) handed circularly polarized beams.Type: GrantFiled: March 6, 1989Date of Patent: January 26, 1993Assignee: Eastman Kodak CompanyInventors: Clark N.
