Patent number: 5293372Abstract: In an information recording/reproducing apparatus, a light beam emitted from a semiconductor laser is guided to a beam splitter. The light beam passing through an incident surface of the splitter is splitted into first and second light beam by a beam splitting layer. The first beam passing through the splitting layer is emerged from a first emerging surface and guided to an optical disk. The first light beam after being reflected from the optical disk is returned to the first emerging surface and passes through the first emerging surface. The returned first light beam passed through a second emerging surface and defected by a detector so that a retrieving signal is generated from a detector. The second light beam reflected from the beam splitting layer is directed to a concave mirror of the splitter and is converged on a mirror detector through a third emerging surface so that a mirror signal for controlling the semiconductor laser is detected.Type: GrantFiled: July 11, 1991Date of Patent: March 8, 1994Assignee: Kabushiki Kaisha ToshibaInventors: Isao Hoshino, Takashi Yoshizawa, Takayuki Asano
