Abstract

본 발명은 양방향 재생 구동이 가능한 테이프의 녹음 재생 장치와 관련된 것으로서, 종래에는 이러한 장치에서 순방향←→역방향 전환시에 공데이타가 존재하는 부위를 재생처리한후 전환되므로서 사용자는 이시간을 무료하고 지루하게 보낼수 밖애 없어 바람직한 것이 못되었으나, 본 발명은 헤드에 공데이타 감지수단(11)과 타이머수단(12)을 구비시키고, 시스템 CPU에는 공데이타 검출시간을 데이타 구분 영역 체크의 1단계와 테이프 고속전진 및 역방향 전환이 2단계로 구별 검출하고 2단계 이후는 테이프의 고속 전진과 역방향 모터를 구동하는 일련의 처리 과정을 갖는 공데이타 자동인식 역방향 제어 프로그램(100)을 탑재시킨 구성의 공데이타 자동인식 역방향 재생 장치 밋 방법을 제공하는데 있다.The present invention relates to a recording and reproducing apparatus of a tape capable of driving a bidirectional reproducing, and in the related art, the user is free of this time since the apparatus converts after reproducing the portion where the blank data exists in the forward ← → reverse direction. The present invention is not preferred because it can not be bored, but the present invention is equipped with a blank data detection means 11 and a timer means 12 in the head, the system CPU has a blank data detection time to the first step of data division area check and tape high speed Automatic detection of forward data with the reverse control program 100 equipped with a blank data automatic detection which has a series of processes for driving forward and reverse motors of the tape. The present invention provides a method for reverse playback apparatus.

Description

Automatic Data Recognition Reverse Playback Device and Method in Recording Playback Device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제4도는 본 발명에 의한 공데이타 자동인식 역방향 재생장치의 시스템 회로 블럭도,4 is a system circuit block diagram of a blank data automatic recognition reverse playback apparatus according to the present invention;

제5도는 제4도와 관련된 동작 프로그램의 일예도.5 is an example of an operation program associated with FIG.

Claims

Data sensing means 11 which detects the data of the tape to be reproduced and reproduced between the head 23 and the subamplifier 25 and provides an active output to the motor reverse direction 27, and the data sensing means 11 The timer 12 is connected between the data detection means 11 and the motor reverse drive unit 27, and is connected between the data sensing means 11 and the motor reverse drive unit 27 to replay at the point after the empty data is detected. A reverse playback apparatus for automatically recognizing blank data in a recording / playback apparatus comprising an FFP key (13) for selecting whether or not to rewind to the end of tape.

A step of setting a blank data detection function to discriminate whether blank data is detected when data is detected during forward playback, and a step of determining whether the interval t _g between recording blocks is zero if blank data is detected; If blank data is detected over time, the step of determining whether the blank data continues for T _g (t _g × 3) time, and if the blank data is detected even after the T _g time passes, reverse play is performed to listen to the playback data. Automatic data recognition reverse playback method in a recording and playback device comprising a step.

3. The method of claim 2, wherein when blank data is detected after a T _g time, the blank data is automatically recognized by a recording / playback apparatus that sets the FFP key to advance the tape at a high speed and automatically reverses it at the end of the tape to listen to data of the next track. Reverse playback method.
