Filed: 1989-12-26
Abstract: PURPOSE:To enable exact supervisory by a new host station by matching the received signal of an old host station with the received signal of the new host station in a monitor mode before switching in the case of switching from the host host station to the new host station. CONSTITUTION:When the host station is exchanged concerning a system mixing four lines and two lines, the flowing directions of respective current paths 4 and 6 for transmission and reception of an old host station 200 are detected by a photocoupler, for example, and the current in the direction corresponding to the OR output of the detection signal is applied to a new host station 200. Therefore, the time of reception is not deviated only for time to reciprocate a signal between the host station 200 and a repeating spot, and the received signals are coincident between the old and new host stations 200 and 100. Further, a current value is prevented from being lowered than a rated value by dividing the current. Thus, the received signal of the old host station 200 can exactly be monitored at the new host station 100.

IPC: G11B7/24018
Filed: 1992-12-18
Abstract: PURPOSE:To attain the recording of a high density with the laser light by forming a recording layer on a substrate that is specified in terms of the thickness, the intra-surface double refraction, the vertical double refraction and sticking those two substrates together with their recording layer sides opposite to each other at the time of production of a recording/reproducing optical disk. CONSTITUTION:The thickness of a substrate is reduced down to 0.4-0.8mm from 1.2mm so that the phase difference and the aberration caused by the double refraction of the substrate can be reduced together with the aberration due to the tilt of a disk. Therefore, an optical disk of such a constitution is available even to the laser beams of 500nm wavelength that are focused by the objective lenses of >0.55 numerical aperture. Thus, the density of the optical disk is increased. That is, the vertical double refraction is set at about 500X10<-6> and the intra-surface double refraction set at about 20X10<-6> or less with use of a general polycarbonate resin. Then, the phase difference produced by the light of 780nm wavelength cast on a substrate of 1.2mm thickness is approximately equal to the phase difference produced by the 500nm wavelength. Thus, the thickness of the substrate can be set at 0.4-0.8mm together with the tilt angle set at 2mrad or less.
