    摘要： Motors drive drive wheels of a motor-driven vehicle. A manual-driving-force sensing unit senses manual driving forces for driving the drive wheels and develops manual-driving-force representative signals. A control unit computes, from the manual-driving-force representative signals, preliminary motor driving signals which, when applied to the respective motors, would make the motors produce mechanical driving forces. The control unit also computes, from the preliminary motor driving signals, compensate motor driving signals to be applied to the respective motors, when the direction of rotation of the motors are the same. Each of the compensated motor driving signals is prepared from the corresponding one of the preliminary motor driving signal with the other of the preliminary motor driving signals taken into account.

    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： 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).
