摘要： An optical recording control method determines an optimum recording laser power by effecting a test recording before information to be recorded is recorded on a disk. The recording laser power is formed of a plurality of powers. A relationship among the plurality of laser powers is regulated by power level ratios between respective powers, whereby a power used when a laser light is radiated on the disk can be controlled to be constant independent of an ambient temperature and a structure of a disk. Therefore, accurate recording marks can be formed on the disk.

摘要： An optical recording/reproducing apparatus includes a plurality of semiconductor lasers, an objective lens for focusing light beams from the semiconductor lasers on an optical disk to form a plurality of light spots, and a correction unit for reducing an offset in a tracking signal occurring concomitantly with relative position correction for the light spots. The correction unit includes a rotary wedge-shaped prism disposed in an optical path through which a laser beam incident on the optical disk and a reflection laser beam from a light spot on the disk pass in opposite directions. The shape, refractive index and initial installation angle of the wedge-shaped prism are designed to have predetermined values that cancel the position shift of the laser beam on the objective lens surface occurring concomitantly with deflection of the laser beam.

摘要： An electron beam memory system in which a phase transition type recording film is used as an information recording medium, and for recording information, a focused electron beam is selectively projected on desired positions of the recording film so as to locally heat the recording film and cause phase transition, while for retrieving information, an electron beam having energy at a degree not causing the phase transition is projected so as to utilize the fact that reflection or diffraction of the primary electron beam projected at the retrieval differs between the recorded regions and unrecorded regions.

摘要： An optical information processing apparatus uses an optical disk having correction marks such as mirror surfaces or wobbled pits intermittently arranged along a guide track. In a reproduce mode, tracking control is effected by correcting a tracking signal by a tracking offset component detected by the correction marks. In a record or erase mode, the track offset correction is deactivated and record or erase operation is controlled in accordance with an output level of the detected track offset component so that incomplete eraser of recorded data is prevented.
