Abstract

PURPOSE:To prevent the generation of a non-recorded part by rewinding a cassette tape until a recorded signal is detected as long as a head detects no recorded signal after the tape is loaded. CONSTITUTION:When a cassette tape is loaded to a rotary head type digital- audio tape recorder R-DAT, a signal detecting means 4 detects whether or not a recorded signal exists at the tape position where a head 1 has a contact. If no recorded signal is detected, the cassette tape is rewound by a rewinding means 7. Then the action of the means 7 is released by a stopping means 8 when a recorded signal is detected by the means 4. Thus the drive of the tape is also stopped. Under such conditions, the tape is set at the termination of the recorded part. Then this recorded part is recorded again and therefore the recording action is carried out without producing any non-recorded part.

In the signal detection means 4, the reproduced signal amplified by the head amplifier 3 is given to an envelope detector 41, and the reproduced signal is subjected to envelope detection and given to a comparator 42. This comparator 42 converts an input with a level higher than a predetermined value into a square shaped wave, triggers a monomultivibrator 43 with this shaped wave, and sends the output of the monomultivibrator 43 to the central processing circuit 5. I can do it. The central processing circuit 5 determines that there is a recording signal when the mono multivibrator 43 outputs continuously.

The operation of the signal detection means 4 having such a configuration will be explained with reference to FIG. In R-DAT, the drum tape is wrapped 90 degrees, so the playback signal is not continuous, and at high speed rewind the drum is about 11,000 rpm, and one revolution is about 60 m5ec. The head 1.1 is switched by the header switching signal shown in FIG. 3(a), and if there is a recording signal on the tape, a reproduced signal as shown in FIG. 3(b) is output. This reproduced signal is subjected to envelope detection as shown in FIG. 3(C), and the waveform is further converted as shown in FIG. 3(d). If the width of the mono-multivibrator 43 pulse output is made longer than the 30m5ec that the drum makes half a revolution, the output of the mono-multivibrator 43 will be continuous as long as there is a recording signal -, as shown in Figure 3(e). .

If there is no recording signal at the tape position where C and C come into contact, the tape is rewound to the end of the green area or the beginning of the tape, and a new recording is made following the green area or to the beginning of the tape. The cassette tape status is displayed appropriately, and no unrecorded parts are created.
The R-DAT operator can know the status of the cassette tape.

If the tape position that the head contacts is in the middle of the recorded song, the tape is fast-forwarded at high speed, and the signal detection means 4 is operated even during this high-speed 1 amount 1 advance, and when the recording signal is no longer detected, the stop means 8 is activated. In this state, with the cassette tape at the beginning of the unrecorded part, a new recording can be made following the already recorded Q part, and the unrecorded part At this high speed, the drum speed is approximately 3000 rpm.
, and one rotation is approximately 20 m5ec. Therefore, if the width of the pulse output of the mono multivibrator 43 is made longer than the half rotation of the drum, the output of the mono multivibrator 43 will be i! if there is a recording signal. It becomes a continuation.

(Effect of IJI+) As explained above, according to the R-DAT recording position control device of the present invention, the presence or absence of recording A and No. 1 at the tape position where the head comes into contact when the cassette tape is loaded is detected by the signal detection means, and if no recording signal is detected, the tape is rewound by the rewinding means, and when the recording signal is detected, the tape is stopped by the stopping means, so that new recording is not possible. Since the recording is performed from the end of the recorded portion (or the beginning of the unrecorded portion), no unrecorded portion is provided, and this has an excellent effect that it is suitable for searching based on information in the TOC area, servo control, ATF, etc.
