Title: Optical pickup
Inventor: HORIGOME HIDEYOSHI
IPC: G11B7/13
Filed: 1988-10-24
Abstract: PURPOSE:To improve the characteristics of an amplitude transmission function MTF by preparing the photodetectors around an objective lens to receive the light diffracted by an optical recording medium. CONSTITUTION:An optical recording medium 7 is irradiated by a reading light beam L2 through an objective lens 6, and a reproduced light beam L3 obtained from the medium 7 is received by a photodetecting lens 6 for transmission of a reproduced signal SRF via an optical pickup. In this pickup the photodetectors 10 are set around the lens 6 at the side of the medium 7 to receive the light L10 which is diffracted by the medium 7. As a result, the aperture number of the lens 6 can be artificially increased. Thus it is possible to improve the characteristics of the MTF and to stably reproduce a compact disk which is recorded with high density in a simple constitution.
