Title: Multibeam optical disk recording and reproducing device
Inventor: HAYASHI AKIO
IPC: G11B7/14
Filed: 1988-12-12
Abstract: PURPOSE:To always obtain a satisfactory tracking state by providing a means which adjusts the angle formed between the beam spot string, which a multibeam light source forms on a recording medium, and a tracking groove on the recording medium. CONSTITUTION:Multibeams emitted from a laser LED 10 are converted to parallel rays by a collimator lens 13 and are reflected on a mirror 14 to form a beam spot string B on a disk D. When a wedge-shaped adjusting tool 16 is moved right or left by an adjusting knob 17 at such a time, a holding tool 12 is rotated as one body together with the LED 10 and a package 11 with the optical axis as the center by cooperation with a spring 18. Consequently, since the spot string B is rotated, the angle of inclination to the tracking groove, namely, the pitch of multitracks is finely adjusted. Thus, the beam spot projected on the disk is accurately matched to the track pitch.

Title: Laser shut-off system in two-way optical transmission system
Inventor: KIHARA TAKASHI
IPC: H04B10/071
Filed: 1988-12-13
Abstract: PURPOSE:To identify whether or not a received optical signal is its own station light and then whether or not a fault exists in an optical fiber system more accurately and to stop optical transmission accurately by providing an up-down counter, a latch and a 3-bit shift register or the like. CONSTITUTION:A 6B code data subject to mark rate modulation is inputted to an up-down counter 41 and count is started by a clock 6BCLK. That is, when logical 1 is inputted, the counter is counted up and when 0 is inputted the counter is counted down, but there is unbalance, then positive or negative count reaches full count after a prescribed time elapses and the processing is repeated via a timing signal TIM. Then a latch 42 fetches an output of the counter 41 to obtain an output of an H level or an L level and the result is inputted to a latch 46 via a 3-bit shift register 43 and NAND gates 44, 45 and its output OUT goes to an H or L level. Thus, whether or not a received optical signal is its own station light is discriminated accurately and whether or not a fault in the optical fiber system exists is identified and the optical transmission is stopped accurately.
