Abstract: When the main power supply is turned off, the power supply of a video display unit is turned off and the audio signal is muted. At the same time, a time counting unit counts time, and before reaching a predetermined time, a display unit is lighted to notify a quick restart period. In the case where the main power supply is turned on during the predetermined time, the power supply of the video display unit is turned on to cancel the audio mute mode. In the case where the main power is not turned on upon lapse of the predetermined time, the power supply of the receiving unit is also turned off.

Abstract: When converting an interlace video signal into a non-interlace video signal by interpolating a scanning line of the interlace video signal, black stretching is carried out with respect to the interpolated scanning line. Thereafter, black stretching is carried out with respect to a non-interpolation scanning line of the converted non-interlace video signal.

Abstract: A magneto-optical disk having recording tracks are formed along concentric grooves or a spiral groove. A non-groove region where no grooves are made is provided in a middle part of each recording track. In the non-groove region, there is formed a pit pattern representing information about the recording track. A track-counting U-groove is formed in the non-groove region, for detecting that the light spot of a reading laser beam has moved across the recording track. With the disk thus structured, it is possible to record information at high density and to access a desired recording track at high speed.

As for a capacity of the spare area in each zone, a predetermined total capacity of spare areas is allocated so that a spare ratio K=D1/D2 of a capacity D2 of the spare areas for a capacity D1 of the data areas becomes almost the same in the zones.

Abstract: Using MSR (magnetically induced super-resolution) technology, a read-head field is applied to a magneto-optical recording medium when reading an information signal from a recording layer of a magneto-optical recording medium, in order to magnetize the read light-irradiated magnetic layer in one direction in a part of an area within the read light spot. The magneto-optical recording medium using MSR technology adopts the on-land recording method in which an information signal is written to the land, which enables read of an information signal by the MSR technology with a smaller read-head field.
