Title: Linear encoder and its manufacture
Inventor: NAKAMURA NOBUAKI
IPC: G01D5/30
Filed: 1988-03-17
Abstract: PURPOSE:To increase the number of pits and to accurately form the pits by forming the arcuate pits which are concentric and nearly with the same length one another by laminating a reflecting member which is formed to pitch D and width D/2, a protection member, and a transparent member. CONSTITUTION:On circles which have radii R1, R2... Rn (n: positive integer) passing the point O of the lengthwise center O-X of a linear encoder 1, the arcuate pits P (P1, P2... Pn) are provided. When the pitches of the pits P are equalized to D, the pits P are formed to the width D/2. Here, those pits are strictly not parts of circles, but parts of spiral shapes, but the pitch D is about 2-4mu although the radii R1, R2... Rn are about 100mm, so they are regarded as parts of circles. Further, the encoder 1 is formed by laminating a protection film 3 made of ultraviolet-ray setting resin, etc., a reflecting film 4 formed by vapor-depositing aluminum, and transparent plastic 5. Consequently, the number of the pits is increased greatly and the pits are accurately formed.

Title: Optical head
Inventor: ITO NOBORU
IPC: G11B7/09
Filed: 1987-03-19
Abstract: PURPOSE:To prevent the track deviation between a recording and reproducing spot and an erasing spot by using a part of an erasing beam to form a narrow address detection spot and indirectly detecting the erasing spot reproducing track address and comparing this address with a recording and reproducing spot reproducing track address to drive an erasing spot driving means. CONSTITUTION:Since a width LT in the track direction of an address detection spot 32 and a width LM of a melt spot 23 are approximately inversely proportional to widths WT and WM of beams in accordance with relations between the spot diameter of the spot formed with a lens and the aperture diameter, the width LT of the address signal spot 32 is reduced by the extent by which the width WT is wider than the width WM. Therefore, the track address is read by the address signal spot 32. The track address of the track which an reading light spot 22 reproduces is detected by the address signal spot 32 and is compared with the track address of the track, which a recording and reproducing spot 10 reproduces, to drive an erasing beam driving means. Thus, the deviation of reproducing track between the erasing spot and the recording and reproducing spot is eliminated.
