Title: Recording and preproducing system
Inventor: OKAMURA SHIROU
IPC: G11B23/22
Filed: 1979-03-23
Abstract: PURPOSE:To make it possible to increase availability of a recording medium by recording data on the surface as well as the reverse face of the magnetic medium where the surface and the reverse face can be used. CONSTITUTION:Magnetic heads 2 and 2' brought into contact with the surface and the reverse face of tape 1 having magnetic films on the surface as well as the reverse face are shifted by angle theta. If this angle theta, tape thickness x, and track width w are determined properly, interference from the tape reverse face is reduced considerably. Thus, tape 1 is casued to run between reels 12 and 12' and is scanned by surface and reverse face heads 2 and 2'. First, only the surface is used, and next, the reverse face is used. When recording is performed on multiple tracks while changing the surface and the reverse face as shown in azimuth (a), availability of the tape is increased considerably. Specially, this system is advantageous to the use of the surface and the reverse face of the same channel for stereo.

IPC: G01C7/04
Filed: 1986-02-19
Abstract: PURPOSE:To accurately detect position data of the scanning line of a laser beam even when a measuring vehicle bounds owing to the projection or recess of a road surface by providing a cylindrical lens on the optical path between a mirror and the 2nd photodetecting element. CONSTITUTION:The cylindrical lens 37 is arranged on the optical path between the position detecting sensor 35 and the mirror 35 which guides the laser beam scanned by respective mirror surfaces of a polygon scanner 22 to the photodetection surface of the position detecting sensor 35 through a mirror 33 arranged so as to photodetect scanning light at the scanning start point of each mirror surface. Even when the laser beam is incident through P3 while the vehicle is at a stop, and even when the laser beam is incident through P4 and P5 owing to the movement of the optical path due to the bound, etc., in the run, the laser beams passing through those optical paths are incident on a fixed position P0 on the photodetection surface of the position detecting sensor 35 all the time. Consequently, the laser beams from a scanner 22 is photodetected with the invariably constant quantity and position data on the scanning line is detected accurately.
