Abstract: A novel recording medium capable of realizing high density, reliability in a recording/reproducing operation and facilitating the process which is performed by a drive apparatus is provided. An amplitude amount of wobbling of a track is made to be 10 nm to 15 nm and a track pitch of the track is made 0.74 &mgr;m to 0.82 &mgr;m. The determined values enable large-capacity recording to be realized and the recording/reproducing performance to be prevented from being deteriorated. As administration information, recommended information for a recording/reproducing operation at an inner peripheral position and an outer peripheral position is recorded. The size of data in a linking section is made to be the same as the sector for constituting a data block.

Abstract: Rhythm sensations can be represented in time to music by using the entire body and to create powerfulness and rhythm sensations. Stepping position indication data which is set by a rhythm setting section is read from a stepping position indication data memory, and the stepping position instruction contents are scrolled and displayed on a monitor by a scroll display control section, thereby performing instructions of the stepping position and the stepping operation timing. When the fact that a player steps on a step-on base section in accordance with the display contents of the monitor is detected by a cable switch and this is input from a stepping operation monitor section, a score proportional to the timing deviation is calculated by an amount-of-deviation detection/totaling section, and next, an evaluation is performed by the rhythm setting section. Then, the next stepping position indication data is set according to the evaluation result.

Abstract: A power unit including a motor is connected to a vehicle body frame. The vehicle body frame extends downward from a head pipe, and is provided with a pair of frames substantially parallel to the ground surface. A control unit receptacle case for driving the motor is fixed to span between the paired right and left frames. Batteries for the supply of electric power to the motor are mounted on the control unit. The control unit serves also as a bottom plate between the paired right and left frames and can carry batteries thereon. Therefore, the use of an additional frame or member for the mounting of batteries is not required, thus permitting a reduction in the vehicle body weight and the number of components used. Since the control unit closes the bottom of the main frame, the rigidity of the main frame is enhanced.

Abstract: An information recording/reproducing apparatus wherein exact reproduction of both wobbled address information and sync information can be realized in a recording mode as well as in a reproduction mode. The apparatus comprises first and second detectors for detecting two diametrical side portions of each track on a recording medium where a pregroove is modulated correspondingly to address information and sync information of mutually different frequency bands; a calculator for calculating a normalized track information signal on the basis of the outputs of the first and second detectors; and a third detector for detecting the address information and/or the sync signal on the basis of the output of the calculator.

Abstract: A magnetic disk drive device that includes a disk-shaped medium with a magnetic film formed on a surface for recording or reproducing information, and a magnetic head for recording on and reproducing information from the disk-shaped medium. The disk-shaped medium has a data recording region and a control signal recording region. The data recording region is impressed to have convex recording regions for recording data and concave guard bands for separating adjacent recording regions. The control signal recording region has impressed concavities and convexities representing tracking marks (for effecting tracking control of the magnetic head), track number indicating marks and track numbers (for identifying the tracks), and clock marks dividing one circumference into equal intervals along a path of angular movement of the magnetic head.

Abstract: In a head displacement measuring method, prior to actual data recording or data reproduction, either one of the recording head and the reproducing head is wobbled, and the test data is recorded in the disk-shaped recording medium by the recording head. Then, the test data is reproduced from the test data by the reproducing head, and displacement between the recording head and the reproducing head is detected on the basis of the reproduced test data. Thus, the displacement may be detected more easily with higher precision than with the conventional optical detecting method.

Abstract: A controlling apparatus for a hybrid car can arbitrarily select whether the hybrid car should be powered principally with an engine or principally with a generator-motor, depending upon driving conditions.

Abstract: An optical reproducing apparatus according to the present invention includes a land/groove switching circuit for alternately switching reproduction of a record mark on a groove portion and a land portion. This allows a tracking operation to be carried out continuously at a connection point to a subsequent track in the recording direction without a laser beam from an optical pickup passing through an end of a spiral track. A recording medium according to the present invention includes a recording track formed of a groove portion and a land portion, and a record mark used for switching a tracking operation so that a light beam emitted from the optical pickup should be irradiated alternately on the groove portion and the land portion. When the record mark is detected, a track jump operation is carried out, and information is reproduced from the groove portion and the land portion alternately.

Abstract: A data for measuring deviation between a recording head and a playback head easily for correctly reproducing data despite such deviation. A playback signal amplitude detection circuit 23 detects the amplitude of playback signals of test data from a playback amplifier 15, while adders 51, 52 cumulatively sum the amplitude values of playback signals in a pre-set group of sectors and those in another pre-set sector of groups on a magnetic disc 21 supplied from the playback signal amplitude detection circuit 23. A subtractor 50 computes a difference between a first sum value from the adder 51 and a second sum value from the adder 52 and routes the difference to a controller 11. The controller detects deviation between the recording head and the playback head from the difference value. When recording or reproducing actual data, the controller 11 causes the position of the recording head or the playback head to be corrected on the basis of the detected deviation.

Abstract: An optical recording method according to the invention is provided such, that when an optical pickup (2) is moved over an optical disk (1), the optical pickup (2) being positioned onto the target track location, record marks are recorded on the optical disk (1) by a light beam irradiated onto the optical disk (1) through the optical pickup (2). An irradiation position of the light beam is offset during recording by a predetermined amount to a track at the recording direction side relative to the target track location, and a record mark is formed on a target track by the offset light beam.

Abstract: The present invention provides a finalization method and apparatus which enables out a reproduction of an optical disk such as a DVD-RAM by using a reproduction apparatus which carries out CLV reproduction. The finalization method according to the present invention includes creating an unrecorded area map of an optical disk on the Logical block address (LBA). In order to execute in the host application a conversion from LBA to Physical Block Address (PBA) which is normally executed in an optical disk drive, a conversion table from LBA to PBA is created. According to this conversion table, the unrecorded area map is converted from LBA into PBA so as to assure the area to be finalized. A dummy data is recorded in the aforementioned assured area of the optical disk.

Abstract: An optical disc, an apparatus and a method for recording/reproducing the optical disc use Gray coded address information. The hexadecimal data 0 to F correspond to the Gray codes. The Gray code consists of the upper address and the lower address. The four channels of the upper address and the four channels of the lower address are set so that one channel of each address is "1". With the change of the data from 0 to F, the channel of "1" in the lower address sequentially moves to the adjacent channel in the corresponding Gray code. Consequently, rapid seeking can be performed by detecting only the lower address.
