Title: Optical information reader from recording carrier
Inventor: NAKADA NAOTAROU
IPC: G11B7/09
Filed: 1983-03-07
Abstract: PURPOSE:To detect accurate values of various servo signals or the like by providing two 4-divided photodetectors in positions where two reading beams divided by a dividing optical system are received and detecting rotation positions of both 4-divided photodetectors around optical axes of reading beams. CONSTITUTION:A beam emitted from a semiconductor laser 1 is so converged that it is focused on a pit face of a disc 6 by a condenser lens system 7 and is reflected. The light passing through an optical axis P is divided to pass through outside optical axes P1 and P2 and is received as inverted semicircular beam spots Q1 and Q2 by 4-divided photodetectors 10 and 11. When received beam spots Q1 and Q2 are operated in an operating circuit, a signal which detects rotation positions of both 4-divided photodetectors 10 and 11 around the optical axis P of a reading beam R is obtained from an output terminal 23a. When an optical information reader is assembled, it is assembled while performing the adjustment until the signal value indicates zero so that both 4-divided photodetectors 10 and 11 are set in prescribed rotation positions around the reading beam optical axis P, that is, a reference line Z becomes vertical (vertical on paper) to a connection line W of both prisms 8 and 9.
