Title: Optical recording medium
Inventor: NAKATANI YOSHIHIKO
IPC: G11B7/243
Filed: 1985-10-09
Abstract: PURPOSE:To permit rewriting of information with a simple method by constituting a recording medium of an alloy system having isothermal bainite transformation and subjecting the alloy to a heat treatment to change the reflectivity of light on the medium surface by the transformation induced by the same. CONSTITUTION:The alloy material having the isothermal bainite transformation entailing surface undulation is used for the recording medium. A thin film 1 having a compsn. consisting of 85 Fe - 15 C is formed on a disk-shaped quartz glass substrate 2 provided with guide grooves and the thin film is formed as an austenite phase. The medium surface of the part irradiated with laser light is finely undulated and the crystal phase is transformed from the austenite phase to bainite phase. The reflectivity in said part is lower by about 27% than the reflectivity of the thin film in the part where the laser light is not irradiated. Namely, the recorded information can be easily reproduced by detecting the reflectivity of the light on the medium surface. The state before recording is restored when the substrate is quickly cooled after the heat treatment at 600 deg.C over the entire part.

IPC: H01S5/06
Filed: 1988-09-09
Abstract: PURPOSE: To obtain a desired relative stability regarding the temperature change of output power, by sufficiently shortening an active region in order not to perform high luminance light emission in a specified operating current range, and generating practical single mode waveguide property suitable for a single mode fiber, in the active region, by the shape of a refractive index structure. CONSTITUTION: An active region is sufficiently short in order not to perform high luminance light emission in the range wherein temperature is at least 10 deg.C, and operation current is 0-100mA. Practical single mode waveguide property suitable for a single mode fiber is generated in the active region, with the shape of a refractive index structure. In order to obtain a side-directional waveguide effect of an edge emission type light emitting diode, rising structure is adopted. In the structure, the effective refractive index of a plane active layer, which is in contact with material having lower refractive index on both surfaces, rises partially on account of the exsistance of an upper extending protrusion of material which invades in material having lower refractive index. Thereby desired relative stability regarding the temperature change of output power can be obtained.
