본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 예정 주파수의 단일 마아크 신호를 포함하는 명령과 마아크를 카세트내의 자기 테이프상에 기록하는 명령 장치의 개략도.
제2도는 제1도의 장치에 의한 명령과 마이크가 기록된 자기 테이프의 개략도.
제3도는 제2도의 자기 테이프상에 기록된 마아크를 형성하는 마아크 신호의 신호 파형의 개략도.

Claims (4)

  1. 공급릴 허브 및 조임릴 허브를 구동시키는 공급 맨드릴 및 조임 맨드릴과, 기록된 신호를 재생시키는 적어도 하나의 자기 헤드와, 자기 헤드에 의해 재생되어 주파수 비교 장치에 적용된 신호의 순간 주파수와 기준 주파수를 비교하여 주어진 상관 조건이 만족스러우면 마아크가 있음을 도시하는 신호를 제공하는 주파수 비교 장치를 구비하며, 정보의 특정 아이템을 확인하는 적어도 하나의 주어진 주파수 마아크 신호를 각각 포함하는 공급릴 허브와 조임릴 허브사이에서 연장되는 자기 테이프상에 정보에 대응하는 정보 신호와 함께 기록되고 기록중에 단지 조임릴 허브만을 경유하여 구동되어 일정한 회전 속도로 구동되는 마아크 검출 시스템에 있어서, 외전 미터가 조임 맨드릴의 회전 속도에 비례하는 주파수를 갖는 회전 신호를 공급하도록 조임 맨드릴에 결합되며, 회전 신호가 회전 신호 주파수가 기준 주파수를 형성하고 회전 신호의 순간 주파수와 자기헤드에 의해 재생된 신호의 순간 주파수를 비교하는 주파수 비교 장치에 공급되는 것을 특징으로 하는 마아크 검출 시스템.
  2. 제1항에 있어서, 상기 주파수 비교 장치는 회전 신호 주파수와 자기 헤드에 의해 재생된 신호 주파수를 비교하기 위해 회전 신호의 순간 주기와 자기 헤드에 의해 재생된 신호의 순간 주기를 결정하고 주기들과 상기 두 주기의 주어진 상관 조건을 비교 확인하여 만족스러우면 마아크가 있음을 도시하는 신호를 제공하는 것이 마이크로 프로세서에 의해 실현되는 것을 특징으로 하는 마아크 검출 시스템.
  3. 제2항에 있어서, 상기 마이크로 프로세서는 회전 신호의 감지된 주기로부터의 상한 주기 및 하한 주기를 갖는 공차 윈도우를 계산하며, 주어진 상관 조건은 자기 헤드에 의해 재생된 신호의 검출된 순간 주기가 상기 두 주기 한계사이에 위치하도록 마이크로 프로세서에 한정되는 것을 특징으로 하는 마아크 검출 시스템.
  4. 제2항 또는 제3항에 있어서, 상기 마이크로 프로세서는 두 주기의 상관 조건이 되풀이하여 만족스러우면 마아크가 있음을 표시하는 신호를 제공하는 것을 특징으로 하는 마아크 검출 시스템.
