Abstract: PURPOSE:To attain a high density recording by reducing the number of blocks constructing a postamble. CONSTITUTION:A block address W1 is detected by a block address remaining block number of the detection circuit 73. The detected block address M1 is calculated in a calculation circuit 75. This is loaded each time of detection of the block address W1 to a counter 74 and counted down with a reproducing word clock. When the 19th block is detected, the output of a comparator 77 is reset to zero, a window pulse WP is raised and therefore, the last PCM audio signal can be detected. When the 19th block cannot be detected, the window pulse WP is raised by counting down the output of the calculation. Thus, the postamble can be correctly detected and accordingly, remaining data not yet erased will not be taken even when the number of blocks of the postamble is reduced and the high density recording can be attained.

Abstract: PURPOSE:To efficiently record the identification code of a sound mode together with a sound signal when the video signal and the sound signal in a certain mode among several sound modes are recorded. CONSTITUTION:There are plural kinds of sound modes used for a High-Vision broadcasting. When the signal of the High-Vision broadcasting is recorded, the sound mode identification signal included in the broadcasting signal is separated and supplied to a system controller, and the system controller generates the 5-bit sound mode identification signal and records it in the sound recording area of a magnetic tape as a control code W2. Since the sound mode identification code (a0 to a3) can identify the recording contents for every two channels of the four channels, a plurality of modes can be identified with a few number of bits.

Abstract: PURPOSE:To excellently carry out signal processing by having an FM demodulator, a means obtaining a prescribed demodulating voltage, and a means carrying out prescribed signal processing to a video signal demodulated by means of the FM demodulator according to the prescribed demodulating voltage. CONSTITUTION:A regenerated signal is supplied to the FM demodulator 2 via an input terminal 1 to be demodulated, and this demodulated signal is taken out to an output terminal via a video processing circuit 3. On the other hand, the demodulated signal from the demodulator 2 is supplied to a synchronization detecting comparator 5, and further, to a holding circuit 6. The circuit 6 is sampled and held with a pulse corresponding to the period of the ampoule part of a PCM sound signal from a terminal 7. This sampled/held signal is supplied to the video processing circuit via the comparator 5. Thus, the frequency of the ampoule part forming a PCM sound part recorded in an adjacent relation to a video signal part is determined to the frequency corresponding to a prescribed voltage, and the signal processing, etc., of the video signal can be excellently carried out through the use of this voltage.

Abstract: PURPOSE:To prevent the generation of deterioration of a sound signal in a principal channel to the utmost by constituting the VTR so that a recording area of the sound signal of a group whose importance degree is high in sound signals consisting of a multi-channel of >=4 channels is placed in a more separated position from the end part in the longitudinal direction of an oblique track. CONSTITUTION:In the case of a high vision broadcast of an MUSE system and a 4-channel stereo voice, a principal voice is a first and a second channels CH1 and CH2. Therefore, on a track pattern on a tape, as for a PCM voice recording area PA12 of a first and a second channels, an area separated more from a track end part of a head scanning start side than a voice recording area after a third channel is allocated, and the areas after the voice recording area become an index signal recording area, a preamble period, and a video signal recording area VA. Accordingly, the higher degree of importance the voice of a channel has, the smaller probability for generating an error becomes, and a sound signal of a high quality is obtained.

Abstract: PROBLEM TO BE SOLVED: To generate correct synchronous pulses by turning off a bit slip countermeasure when a tape is reproduced at a different speed from that when the tape is recorded. SOLUTION: In a transition state by a state machine, a width of a detection window at a synchronous window generation circuit 7 is changed, for example, by letting a CPU controlling a digital video tape recorder turn on/off a bit slip countermeasure from outside. When a tape runs at a normal recording speed, the bit slip countermeasure is switched on, so that the detection window of, e.g. a ±3-clock width to a 750-clock position is generated. On the other hand, if the tape is reproduced at a speed different from that at the recording time, the bit slip countermeasure is turned off, and the detection window of a ±0 width to the 750-clock position is generated. Accordingly, the generation of wrong FWSYNC pulses because of a false synchronization is suppressed.
