Abstract: PROBLEM TO BE SOLVED: To increase linear recording density and to increase recording capacity of a medium by forming a prescribed relation among the shortest pit interval along a scan direction of a read-out light beam, the wavelength of the read-out light beam and a numerical aperture of an objective lens. SOLUTION: An optical recording medium forming a phase pit according to a signal and changing a reflectance according to a temperature is irradiated by the read-out light beam, and the phase pit is read while partially changing the reflectance in the scan spot of the read-out light beam. In such a optical recording medium, the shortest phase pit interval of a recording signal along the scan direction of the read-out light beam is made λ/2NA or below when the wavelength of the read-out light beam is defined λ, the numerical aperture of the objective lens is NA. By such a optical recording medium, recording density in the scan direction of the light beam of a laser beam, etc., that is, the linear recording density, is increased by making a pit arrangement interval (recording pit interval) in this direction λ/2NA or below.

Abstract: PURPOSE:To simplify the assembly by constituting the amplifier circuit with a series circuit comprising a resistor and a capacitor with a comparatively small capacitance connecting to an amplifier in negative feedback connection and a comparator whose couple of comparison input terminals are connected to the connecting point between the resistor and the capacitor of the series circuit and a reference potential respectively and whose output terminal is connected to the amplifier. CONSTITUTION:The circuit consists of an amplifier A whose closed loop gain is controlled by negative feedback resistors R0, R1 a comparator CP, a constant current source CCS, a reference potential source whose voltage is a 1/2 of a power supply voltage VCC, and a 1st series circuit whose one terminal is connected to the resistor R2 connecting to an output terminal of the amplifier A and whose other terminal is connected to a chip capacitor C1 with a comparatively small capacitance connecting to and output terminal of the amplifier A, and a 2nd series circuit comprising a capacitor C2 and a resistor R3 whose one terminal is connected to the output terminal of the amplifier A and whose other terminal is connected to the reference potential. The comparator CP is not active to an AC signal of a prescribed frequency band but acts like reducing an output offset voltage only to one over the transit gain of the comparator CP thereby applying offset compensation. Thus, a capacitor of a large capacitance for offset compensation is not required, and the assembly process is simplified.

Abstract: PURPOSE:To effectively use the performance of an optical disk controller part to omit an optical disk controller part for extension by controlling the optical disk drive part of an auto-changer type optical disk device for extension by the optical disk controller part in the connection destination. CONSTITUTION:When optical disk drives 5a and 5b are driven, they are set to the SCSI ID number of an optical disk controller 4 of an optical disk device 2. The optical disk drive to be used is switched by the logical unit number, and optical disk drives 5a and 5b of both of devices 1 and 2 are controlled by the optical disk controller 4. Two auto-changer type optical disk devices are used by switching among three kinds of SCSI ID number in this manner. Thus, the number of the other devices to be connected on an SCSI bus is increased by reduction of the number of SCSI ID numbers by one. Since the optical disk extending device 1 does not require the optical disk controller, the cost is reduced.

Title: Optical branching filter
Inventor: SUZUKI TOSHIAKI
IPC: G02B6/293
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an element which can select light different in wavelengths with simple constitution by branching wavelength multiplex light into the light of the plural different wavelengths through the use of one filter. SOLUTION: The light of the plural different wavelengths can be obtained by making plural wavelength multiple light incident on the filter whose transmission wavelength changes when the incident angle of incident light changes like an interference filter at different angles. The wavelength multiplex signal light which is made incident on an optical fiber 101 and is distributed in a star coupler 102 is made incident on 106 from the left from a fiber 103. Then, it reaches the interference filter 113. Since the incident angle to the interference filter 113 becomes smaller as light transmits from the fiber 103 to 106, the transmission wavelengths become different. Generally, the transmission wavelengths become longer as an angle formed by a filter face and light becomes smaller.  Namely, the angle formed by the optical fiber and the interference filter can be set to a value sufficient for separating the transmission wavelengths.
