摘要： An alarm device for a vehicle comprises sensors for detecting abnormal states of the vehicle, a logic circuit for receiving the outputs of the sensors and producing one or more alarm speech designation signals and an alarm speech generator responsive to the alarm designation signal. The logic circuit includes a priority circuit for determining the order of precedence of the abnormal states represented by the detection signals on the basis of the degree of emergency, so that the alarm speech is concerned with the most emergent alarm when two or more abnormal states are detected simultaneously. The logic circuit may further include a switch circuit for disabling at least one of the detection signals so that a vehicle driver having taken notice of particular alarms is not disturbed by excessive alarming.

摘要： A tracking servo system for a magnetic recording and reproducing apparatus uses a flexible magnetic disk having thereon at least first, second and third tracks each of which includes a data track portion and a pair of servo track portions located on both sides of the data track portion. Tracking signals having different frequencies are recorded on the first, second and third servo track pairs. Servo and data heads are formed in a unitary structure. When the data head records an information signal on the second data track portion or reads out the recorded information signal therefrom, the servo head reads out the tracking signals recorded on the first and third servo track portions.

The apparatus is automatically adjusted to each individual magnetic tape in use in such a manner that: a first test signal from the source is recorded on a magnetic tape with a preset bias control signal, the recorded first test signal is reproduced, the bias control signal is adjusted to provide a maximum HF saturation level and a minimum distortion to thereby determine an optimum bias control signal, and the proper bias control signal is fixed for said bias generating circuit; another test signal from the source is recorded on the magnetic tape with a preset gain control signal, the recorded other test signal is reproduced and is compared with a reference value at the operating circuit unit to provide an error signal, and the resulting error signal is fed through the memory to the control unit to renew the preset gain control signal for said amplifier. The adjustment of the frequency response control signal for the equalizer is effected in the same manner as the adjustment of the gain control signal.

摘要： A disk-shaped recording medium recording/reproducing method for performing a data recording operation and a data reproducing operation to the disk-shaped recording medium alternately includes identifying whether a recording area at an ending point of an n-th recording operation on the disk-shaped recording medium, where n is a natural number, is continuous to a recording area at a starting point of (n+1) recording operation. In response to an identifying result indicative of discontinuation of the recording area in the identifying step, the rotational speed of the disk-shaped recording medium is changed to a rotational speed at the starting point of the (n+1)th recording operation, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation.

摘要： A recording/playback apparatus including a stationary drum on which a traveling magnetic tape is wound, a plurality of magnetic heads for recording and playing back data, a rotary portion which is rotated while carrying the heads thereon, a drive portion which drives the rotary portion, an air injection device which spouts air from the vicinities of the magnetic heads toward the magnetic tape in order to separate the tape from the heads, and a control device which controls the start and stop of the air spouting of the air injection device. In the standby mode of the apparatus, in which the rotary portion is rotated though the heads perform neither the recording nor the playback operation, the tape is separated from the heads, so that the heads are prevented from wearing away. As soon as the standby mode has ended, the tape is brought into contact with the heads, so that the recording or playback operation can be immediately started.
