Abstract

The present invention relates to a method of controlling the recording of a track record of a tape recorder, in particular, when re-recording on a tape that has been recorded more than once, so that a certain area that is not erased is skipped to be recorded so as to be suitable for protecting a user's necessary data. It is.

The conventional technology has a problem in that, when recording on a tape once recorded, even if there is no data to be erased and there is data to be protected, it cannot be precisely located at the time of re-recording. .

Therefore, the present invention protects the necessary data by checking the recording time of a plurality of data already recorded on the tape and performing fast forwarding for the predetermined recording area designated to be tracked by comparing the recording time.

The present invention relates to a method of controlling the recording of a song track of an audio tape recorder. Especially, when re-recording on a tape recorded more than once, it is suitable for protecting a user's necessary data by skipping a certain area that is not desired to be erased. I did it.

The conventional audio tape recorder does not want to be erased when re-recording on the tape once recorded, and even if there is data to be protected, the position cannot be accurately determined when re-recording, so it is not protected and erased due to the operator's trouble. There was this.

Therefore, the present invention is to protect the required data by checking the recording time of a plurality of data already recorded on the tape, and by performing a fast forward for the predetermined recording area designated to be tracked by the comparison of the recording time. When described in detail by the accompanying drawings as follows.

FIG. 1 is a block diagram showing the configuration of an apparatus for controlling recording of a song track of an audio tape recorder according to the present invention. As shown in the drawing, first, a cassette 11 for protecting a tape and a voice data can be recorded and reproduced. A tape 12 carrying auxiliary data containing data, retrieval and other information of the recorder, a recording / reproducing head 13 for recording and reproducing main data and auxiliary data, and recording and reproducing data on the tape. A recording / playback section 14 including main circuits such as a recording / playback amplifier section, a digital signal processing section, an analog / digital or digital / analog conversion section, and a cassette and a recording / playback head. Mechanism control unit 15 for controlling driving and a system for controlling a system by receiving a key input selected by a user and instructing a display or the like By having a fisherman 16 and, Wolgok function selection keys and the ENTER key, etc. Wolgok haejugo set the various modes to the system control unit comprises a recording and reproducing mode setting unit 17 for display to the display device to receive the data again.

2 is a flowchart illustrating a method of controlling the song recording of the audio tape recorder according to the present invention. As shown in the figure, the song is played using the new song function selection key and the song designation key provided in the recording / playback mode setting unit 17. A system memory by calculating a recording mode of the music playing mode (S1) for instructing recording to the mode and designating a data protection area to be song-processed, and a recording time of the music playing area and the recording time of the music playing area before the song playing mode is set; The recording time calculation and storage step (S2) stored in the memory and the mechanism control unit instructs the recording operation in the Wolgok mode, and the Wolgok, which checks whether the record time before the Wolgok area has elapsed while recording with normal winding according to the recording format. After recording the previous region (S3-S5) and the recording time of the previous region, fast forward as much as the recording time Skip region skipping step (S6, S7), which skips the data protection area and stores the input data in the memory during the fast-forward time, and checks whether the song region recording time has elapsed; The recording is performed after the Wolgok region recording step (S8, S9) which sequentially reads the data stored during the fast-forward time and records the data in the normal winding according to the recording format.

The operation and effects of the present invention made as described above are as follows.

As an example, when the data configuration state recorded more than once on a blank tape is as shown in FIG. 3, and the fifth (T5) data is to be protected, the recording / playback mode setting is performed as shown in the flowchart of FIG. The user sets the recording in the moon valley mode by the newly provided moon valley function selection key and the moon valley key from step 17 (step S1), and the moon phase is displayed on the display and a number indicating the position is displayed to indicate the moon valley. The fifth data is selected with the key.

Accordingly, the recording time of each song number data recorded in the auxiliary data area while being recorded at least once by the microprocessor in the system controller 16 is fetched into the internal register, and then the previous area of the fifth data indicated after the instruction is fetched. That is, the first, second, third, and fourth data recording times T1-T4 are summed (T1 + T2 + T3 + T4), and the time is stored (step S2).

Here, the recording time of each song number data is recorded in the auxiliary data area of the tape 12, which is recorded together with the main data at the time of recording.

Thereafter, the mechanism control unit 15 instructs recording of the waeggok (step S3) and performs recording in accordance with the recording format by the normal winding until the time before the waegok area recording time (T1 + T2 + T3 + T4) elapses (step S4, S5), if the recording time of the previous song has elapsed, the newly recorded data is stored in the temporary memory while the new song is skipped with a high-speed rewind (steps S6, S7) during the song recording time (T5). When the elapsed time, the data stored in memory until the end of recording is sequentially recorded by the normal winding (steps S8 and S9). When the recording is finished, the mechanism control unit 15 stops the operation (step S10). Complete the recording.

As described above, the present invention uses the recording time of the data to be protected and the previous recording time recorded in the auxiliary data on the tape to re-record normally until the previous recording time, and the user can play the music with a high-speed winding as the recording time of the data to be protected. Can protect the data you want to protect arbitrarily.
