Title: Optical recording medium driving device
Inventor: KANAZAWA YASUNORI
IPC: G11B11/105
Filed: 1988-06-20
Abstract: PURPOSE:To reduce a manufacture cost and to cause an optical recording medium driving device to be compact by arranging an optical crystal body having optical anisotropy, whose thickness is shaped so that an incident light flux can be split in the direction of an optical axis to be divided into two light fluxes and the two divided light fluxes can obtain a desired interval, in an optical head. CONSTITUTION:As a means to divid an outgoing light from a laser light source 1, an optical crystal body 12 is arranged in the incident side of an objective lens 6. The optical crystal body 12 uses a crystal, which has the optical anisotropy, with splitting it in the direction of the optical axis, in which the incident light is divided into the two light fluxes of a normal light beam 21 and an abnormal light beam 22. The thickness of this optical crystal body 12 is shaped so that two light spots 23 and 24 can be image-formed on amagneto-optical film 8 with the desired interval. Accordingly, the two spots 23 and 24, which are needed for the recording, erasing and reproducing of information, can be image-formed on the recording surface of an optical recording medium. Thus, the manufacture cost can be reduced and the device can be made compact.
