摘要： In one embodiment, the optical read/write apparatus includes a plurality of optical pickups arranged to cross tracks of an optical storage medium and a control section. On finding the data that has been written by any of those optical pickups inaccurate or on detecting any defect at a location where data is going to be written by any of the optical pickups, the control section instructs another one of the optical pickups to write that data on a different track from a track on which the data should have been written.

A lens holding member holding an objective lens and a housing are simultaneously and integrally molded through four linear spring members inserted in a die. Afterwards, a pair of magnets are fixed on the lens holding member, and an electromagnetic coil is wound, and wire terminals are wound in the wire arrangement grooves, then a soldered coil frame is fixed on the housing. A brake member is injected into the recess space enclosing linear spring members with the inside of the side wall of the housing and the inner wall, the brake frame, its partition wall, and part of the coil frame, from the side surfaces. The objective lens is mounted on the middle and top of the lens holding member holding the objective lens, and an optical plate is fixed in the middle of the lower surface, thereby forming a rigid nearly hexahedral structure, in which the suspension center by the linear spring members and the driving center by the driving system of the electromagnetic coil and magnets are matched, and the moment balance of the lens holding member including the objective lens and optical plate is achieved on this driving center.

摘要： Optical-beam 2 emitted from semiconductor laser device 1 is transformed into parallel-light 4 by means of collimator lens 3, and a part of parallel-light 4 passed through parallel glass-plate 7 of which the front-surface is mirror finished and the rear-surface is frost finished is inputted into detector 5 monitoring the light-quantity. The optical-beam reflected from parallel glass-plate 7 is focused on information medium 9 after it passed through a collimator-lens 6. The optical-beam reflected from information medium 9 is then introduced on a detector disposed on the semiconductor laser device taking an reversed course. Since no interference of light transmitted through detector 5 is generated in this optical head, a higher linearity of the output of detector 5 can be obtained so that the better stabilized output control of semiconductor laser device 1 by means of laser control circuit 11 can be obtained.

摘要： A light intensity control device of the present invention includes a light source for outputting a plurality of types of light beams having different wavelengths; a light receiving section for receiving and converting the light beams into an electric signal in accordance with the intensity of the respective light beam; and a polarization separation section provided between the light source and the light receiving section. The plurality of types of light beams include a first light beam and a second light beam having a longer wavelength than that of the first light beam. The polarization separation section guides both a first polarization direction light component of the second light beam and a second polarization direction light component, perpendicular to the first polarization direction, of the second light beam to the light receiving section. The polarization separation section guides a first polarization direction light component of the first light beam to the light receiving section, and suppresses a second polarization direction component, perpendicular to the first polarization direction, of the first light beam from advancing to the light receiving section.
