Title: Master disk exposing device for optical disk
Inventor: MORIMOTO TAKAO
IPC: G11B7/26
Filed: 1989-06-26
Abstract: PURPOSE:To remove the unstabilization of an optical spot position or light intensity distribution due to a change in the optical axis of an objective lens by reflecting objective lens inclination detecting light by an optical thin film formed on one side of the objective lens and detecting the reflected light by an objective lens inclination detecting means. CONSTITUTION:The objective lens 10 is coated with a half reflecting face optical thin film 11 having a property for transmitting the wavelength of focus exposing light (a) and reflecting the wavelength of an objective lens inclination detecting light (b). Thereby, the light (b) is reflected by the half reflecting face 11, converged by a condensor lens 14 and led into a 4-divided photodetecting element 15. When the optical axis of the objective lens 10 is inclined by theta from the optical axis 19 of the incident light, the reflected objective lens inclination detecting light (b) is turned to a reflected light axis 20 inclined by the shear of the curvature center of the face 11, so that the inclined state can be detected from the difference of photodetecting values. Consequently, the position of an optical spot or light intensity distribution can always be stabilized.

Title: Discriminating circuit for efm signal and other signals
Inventor: GOTO HIROYUKI
IPC: H04L27/14
Filed: 1986-07-11
Abstract: PURPOSE:To satisfactorily discriminate an EFM signal from other signals by detecting the EFM signal of combination of pulses having widths 3-11 times as much as the cycle of a bit clock by means of a retriggerable monostable multivibrator, a monostable multivibrator, an AND gate, etc., in response to each pulse width. CONSTITUTION:The widths of pulses forming the EFM signal to be transmitted via a binarization circuit 3 are detected by a retriggerable monostable multivibrator which shortens slightly the pulse width and monostable multivibrators RMMa1, MM1-RMMan and MMan. Then the pulses corresponding to the leading of those pulses passing through NAND gates Na1-Nan are supplied to trigger the retriggerable monostable multivibrators RMMb1-RMMbn. Thus a pulse corresponding to a combination pulse having a slightly larger width is outputted. An NAND gate Nb contains each combination pulse and outputs the detection output of the EFM signal only when all multivibrators RMMb1-RMMbn are outputted. Thus it is possible to satisfactorily discriminate an EFM signal from other signals including some pulses of corresponding widths.
