Abstract

Disclosed is a continuous record control method for a tape recorder. The method includes a first step which records an input data to a predetermined section(N), a second step which records a record completion signal on the last section(N+1) recorded, a third step which an user inputs a continuous record mode, a fourth step which detects the record position of the record stop by running the tape in a high speed, and a fifth step which records again at the record completion signal record position. Thus, the loss of data can be reduced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape recorder, and more particularly, to a method and an apparatus for controlling a control recording of a tape recorder capable of detecting the last recording position on an audio tape and connecting the recording to the correct position.

A conventional tape recorder will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of a conventional tape recorder. The input data input from a microphone or other audio device and the output data output from an earphone, a speaker, or the like are pre-amplifier. A recording / playback section 1 for processing with Dolby IC, a bass IC, a power amplifier, a recording / playback head 2 for recording and reproducing the magnetic tape 4, and a magnetic tape 4 ), A mechanism control unit 5 which controls the running of the tape according to the command of the system control unit, and informs the system control unit 6 whether the tape is near the end, and the mechanism control unit 5 System control unit 6, presenting the driving mode to the control unit, and instructing the recording / reproducing unit 1 in the recording mode reproducing mode, and performing motor, mode, block control, cassette, plug-in / out-sensing, and the like. For Are user-configurable to the recording and playback mode setting unit (7) so as to enter a command.

However, in the conventional tape recorder, the tape is divided into the magnetic region 9 and the non-magnetic region 10 as shown in FIG. 2, so that the tape end portion can be checked, but the portion of the tape is recorded when recording to the tape recorder. After re-recording, the last recorded position cannot be detected and accurate connection recording is impossible, resulting in increased data quality and power consumption.

The present invention has been made to solve the above problems, and an object thereof is to provide a connection recording control method and apparatus that can be quickly connected recording to the correct position.

The tape recorder connection recording method and apparatus of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

3 is a block diagram of a tape recorder continuous recording control device according to the present invention, which generates a recording end signal at a last position recorded to a predetermined position by receiving a command from the system control unit 6 of a conventional tape recorder. A recording end signal generation and detection unit (8) for recording through 1) and detecting the position where the recording end signal is recorded during continuous recording is added.

The tape recorder continuous recording control method of the present invention configured as described above will be described with reference to FIG. 3 and FIG. 4, which is a continuous recording data configuration diagram of another tape according to the present invention, and FIG.

First, assuming that the user has recorded the constant input data to the position of N on the A surface as shown in FIG. 4, the system control unit 6 instructs the recording end signal generation and detection unit 8 to generate the recording end signal and ends the recording. The signal generation and detection section 8 generates a signal corresponding to the portion hatched at the position of N + 1, and instructs the recording and playback section 1 to record.

Therefore, the recording end signal is recorded at the position of N + 1.

Then, if the user wants to continuously record another data from the position of N + 1, the user inputs the continuous recording mode through the recording / playback mode setting section 7.

Then, the system control unit 6 instructs the mechanism control unit 5 and the recording end signal generation and detection unit 8 so that the mechanism control unit 5 controls the running of the tape and the recording end signal generation and detection unit 8 records the end signal. Search to detect the position where the recording end signal is recorded.

The search is performed in a search forward mode for audio muting in the FF mode or a search reverse mode for audio muting in the REW mode.

When the recording end signal generation and detection unit 8 detects the recording end signal at the N + 1 position, the mechanism control unit 5 stops the running of the tape and starts continuous recording at that position.

In this way, since recording starts at the hatched N + 1 position, the recording end signal automatically overwritten during continuous recording is removed.

As described above, in the tape recorder continuous recording method and apparatus of the present invention, the recording end signal is recorded at the last recorded position, and the previous recording is performed by detecting the position where the recording end signal is recorded during continuous recording and recording the position again. It has the effect of avoiding data corruption.
