摘要： In an objective lens actuator, when an action force generation force including a focus coil and a magnetic circuit generates an action force for displacing an objective lens holder in a focus direction of an optical disk, a leaf spring supports the magnetic circuit with respect to an actuator base, in such a manner that the magnetic circuit can be rotated about an arbitrary point in the leaf spring, by a reaction force of the action force. At the same time, the equation a=I/Mh is satisfied, where M is a mass of the magnetic circuit, I is a moment of inertia of the magnetic circuit about a center of gravity, a is a distance between the center of gravity of the magnetic circuit and a line of action in a direction of the action force, and h is a distance between a center of rotation in the leaf spring and the center of gravity of the magnetic circuit. As a result, even if the reaction force of the action force acting on the objective lens holder is generated, stable focus servo can be performed, and the actuator can be downsized with a simple structure.

摘要： A multi-beam optical head includes a plurality of light sources for emitting a plurality of light beams. An optical system for irradiating the light beams onto the recording surface of a recording medium is included and receives the light beams reflected from the recording medium. The optical system includes a reflecting mirror for directing the light beams emitted from the light sources toward the recording medium; a photodetector for detecting the light beams received by the optical system and for generating electric signals based on the detected light beams; and rotational controller for controlling the reflecting mirror to rotate around an axis which is perpendicular to the recording surface by an amount determined based on the electric signals. The reflecting mirror positions the light beams on tracks on the recording surface of the recording medium. The tracks are tracks on which information is recorded from which the information is reproduced.

摘要： The magnetic head of the present invention includes a magnetic body in the form of a flat plate, and a magnetic pole in the form of a pillar for applying a magnetic field to a recording medium, which is provided to rise on a portion of the magnetic body which is offset in one direction from a center of the magnetic body, and is provided with a coil around its outer periphery. Thus, the magnetic head has a core of a raised shape which is composed of the pillar-shaped magnetic pole being attached to the magnetic body in the form of a flat plate, making it possible to provide a heat capacity and a heat radiation area required for the core and the magnetic body, respectively, thus adapting to high frequencies. Further, because the magnetic pole is provided on a position which is offset in one direction from the center of the magnetic body, there will be no interference between the magnetic head and the cartridge or mechanical components even when the size of the core is increased due to the core of the raised shape. As a result, less restriction is imposed on a moving range of the magnetic head, thus using the entire recording area of the recording medium.
