Title: Optical disk recording and reproducing method
Inventor: OBARA KAZUAKI
IPC: G11B7/00
Filed: 1985-06-26
Abstract: PURPOSE:To improve the recording linear density, even when a conventional optical system or semiconductor laser is used, by representing the information by using plural kinds of marks having an equal length and each different shape, and recording and reproducing this mark on an optical disk recording medium. CONSTITUTION:When an output of comparators 15, 16 and an output of a D flip-flop are inputted to a logical circuit constituted by using AND circuits 27, 29 and NOR circuits 30, 31, signals of output terminals 36-39 are varied as shown by figures (N)-(Q). That is, by a waveform 9, an output of an AND circuit 28 becomes a high level as shown by a figure (O), and by a waveform 10, an output of the AND circuit 27 becomes a high level as shown by a figure (N), and by a waveform 11, an output of the AND circuit 29 becomes a high level as shown by a figure (P), and by a waveform 12, an output of the NOR circuit 30 becomes a high level as shown by a figure (Q). In this way, four kinds of different mark shapes provided on an optical disk can be detected, and an information quantity of 2 bits can be assigned with regard to one mark, therefore, a linear density of the optical disk can be improved.

Title: Optical coupler
Inventor: TAKAMATSU MICHIHIRO
IPC: G02B6/28
Filed: 1986-06-16
Abstract: PURPOSE:To sufficiently suppress the deterioration of coupling loss and to improve the transmission characteristics of an optical signal by converting a geometro-optic angular shear generated between incident light and an optical branching/coupler into parallel movement in the projecting direction. CONSTITUTION:A light beam projected from an optical fiber 38 is transmitted to a coupler film 48 as incident light through lenses 26, 22a. A part of the incident light is penetrated through the coupler film 48 as it is and transmitted to an optical fiber 42 through a lens 30. On the other hand, a part of the incident light is reflected by the coupler film 48, reflected by a side 22c and transmitted to an optical fiber 46 through a lens 34. Namely when it is defined that a side 22a is an incident part and sides 21b, 22b are projection parts, the light beam obtained from the optical fiber 38 can be branched into two beams. Even if a set angle theta is sheared by temperature change or the like after adjusting the optical axis of the optical branching/coupler 20, the shear of the angle theta can be converted into the shear of the axis, so that the coupling loss can be sufficiently suppressed.
