    摘要： An optical disk according to the present invention has data recording tracks of lands and grooves. Each of the data recording tracks has a length corresponding to a revolution of the disk and includes a plurality of track sectors. The data recording tracks of lands and grooves are connected alternately to form a continuous data recording spiral. Each of the track sectors has a preformatted identification signal part for representing sector address data and has a data recording part for recording data. The identification signal part has a first address data region and a second address region. The first address data region and the second address data region are shifted by the same predetermined distance in opposite directions from the center of a groove track in the radial direction of the disk. The first address data region is set to represent the address of a groove track sector, and the second address data region is set to represent the address of a land track sector adjacent to the groove track sector.

    摘要： In an optical disk drive apparatus for recording data on and reproducing data from an optical disk using both of data recording tracks formed of grooves and lands, is divided into an integer number of sectors, and the address data area of each sector is shifted in the radial direction. When a first sector is scanned, a data from the address data area of the first sector is read as a first direct address data, and a data from the address data area of an adjacent sector is read as a second direct address data. A first modified address data of the first sector is produced by modifying the second direct address data with an inter-track address difference, and a correct address value of the first sector is produced using the first direct address data and the first modified address data.

    摘要： A control apparatus for a motor-driven vehicle driven by a motor brakes the vehicle without giving shock to the vehicle. The control apparatus includes a vehicle maneuvering section for sensing a manual driving force as applied to it. The control apparatus also includes a control circuit which, when a manual driving force for driving the vehicle is applied to the maneuvering section, causes the motor to provide a mechanical driving force for the vehicle in accordance with the sensed manual driving force. The control circuit includes a braking force providing device which gradually increases a braking force for braking the vehicle from zero when manual driving force has been removed from the maneuvering section.

    摘要： A disc apparatus includes a readout unit, an audio signal output unit, a memory, a switch, and a controller. The readout unit reads out data from a disc wherein the data includes at least digital audio data. The audio signal output unit produces an audio signal output in accordance with the digital audio data. The memory stores the digital audio data read from the disc by the readout unit. The switch switches the digital audio data supplied to the audio signal output unit between the digital audio data stored in the memory and the digital audio data currently being read by the readout unit. Furthermore, the controller controls the readout unit and the memory so that, prior to a playback start operation, the digital audio data of a first predetermined period from a beginning of at least one program is read out by the readout unit and stored in the memory; controls the switch so that, at a beginning of the playback start operation, the audio signal output unit produces the audio signal output based on the digital audio data stored in the memory; and controls the switch so that, a second predetermined period after the start operation, the audio signal output unit produces the audio signal output based on the digital audio data currently being read out by the readout unit.

    摘要： A magnetic recorder/reproducer converts two-channel analog signals into digital signals by a sample-and-hold/A-D converter circuit (3) and controls addresses in a memory circuit (4) by a memory address control circuit (5), to distribute the digital signals into odd sample groups and even sample groups per each channel for arraying the odd sample groups and the even sample groups of the same channel in alternate scanning intervals, thereby to write the same in the memory circuit so that the odd samples and the even samples of the same channel are arrayed in positions separated from each other along the direction of scanning by rotary heads (10, 11). The digital signals thus permutated are modulated by a modulation circuit (7), to be recorded in a magnetic tape by the rotary heads. The digital signals reproduced by the rotary heads are demodulated by a demodulation circuit (14), to be stored in a memory circuit (15). A memory address control circuit (16) controls addresses so as to permutate samples of the reproduced digital signals stored in the memory circuit to be in the original array thereof. The reproduced digital signals read from the memory circuit are converted into analog signals by a D-A converter (18), to be outputted through a low-pass filter (19).
