摘要： An optical disc apparatus capable of reducing looseness vibrations resulting from a gap between a sub-guide shaft and a bearing is provided. According to an optical disc apparatus in the present invention, both ends of the sub-guide shaft are supported by being sandwiched between a pair of support parts formed in a chassis and a pair of pressing members mounted on the chassis. The support part is formed by bending a protruding portion both protruding in an inward direction of a hole from an edge of the hole of the chassis and extending along the direction perpendicular to the sub-guide shaft.

摘要： Various apparatuses and methods for laser positioning in an optical disc drive are provided. In one embodiment, a laser positioning apparatus is provided in which a first positioning assembly positions a first laser beam generated by a first laser and directed toward a first side of an optical disc site in the optical disc drive. A second positioning assembly positions a second laser beam generated by a second laser and directed toward a second side of the optical disc site in the optical disc drive. The second positioning assembly positions the second laser beam independent of the positioning of first laser beam by the first positioning assembly, the second positioning assembly further comprising an actuator that positions the second laser beam, and an elastic member that opposes a movement of the actuator.

摘要： Information about the number of traversed tracks is acquired with a code at a first rotational speed and a second rotational speed in each area provided by dividing one rotation into m (m is a natural number equal to or larger than 1). As to the information about the number of traversed tracks, a difference is calculated between the areas. A value proportionate to the sum of absolute values of the information about the traversed tracks in the areas is used as a vibration detection value proportionate to vibration amplitude.

摘要： The present invention relates to a feed screw driving apparatus that moves a power transmission member, which engages a feed screw, in an axial direction of the feed screw by rotationally driving the feed screw using a driving source, such as an electric motor, and also to an information recording and/or reproducing apparatus that moves a pick-up apparatus with this feed screw driving apparatus and records and/or reproduces an information signal onto or from a disc-like recording mediumIn a feed screw driving apparatus that moves a power transmission member, which engages a feed screw, in an axial direction of the feed screw by rotationally driving the feed screw using a driving source, there is provided an elastic member that energizes the power transmission member in the axial direction of the feed screw.The gap between the feed nut and the feed screw is eliminated, so that the feed screw can be driven at high speed without driving errors (play) being produced and the driving of a slide member can be controlled with high precision.

摘要： A system and method for performing seek or jump functions in a digitally stored audiovisual file are described. When the audiovisual file is recorded onto a storage medium, headers, which are distinct and separable from the audiovisual file datastream, are set in the audiovisual file in the storage medium. Each header contains a timestamp. When jumping/seeking, an estimated position for the desired timepoint on the storage medium is calculated by multiplying the storage unit per time unit rate by the desired timepoint. Then the system and method jumps to the estimated position, where the timestamp in the nearest header is checked to determine whether the time it indicates is close enough to the desired timepoint. If it is not, a new estimated position is calculated and the method repeats until either an iteration limit is reached or the estimated position is determined to be close enough to the desired timepoint.
