Abstract

본 발명은 마그네틱이나 광 기록시스템에 있어서 제일 많은 에러를 발생키는 특정 입력 패턴을 제외한 변조코드를 룩 업 테이블화한 기록 시스템을 위한 코딩장치에관한 것이다.The present invention relates to a coding apparatus for a recording system in which a modulation code excluding a specific input pattern causing a greatest error in a magnetic or optical recording system is made look-up table.

본 발명은 특정비트의 입력 데이타를 어드레스로하여 에러를 발생시키지 않는 해당 코드워드 값을 일정비트로써 기록 매체(10)(10A)로 출력하는 룩-업 테이블 (10)(10A)로 구성된다.The present invention comprises a look-up table 10 (10A) for outputting a corresponding code word value which does not cause an error with an input data of a specific bit as a certain bit to the recording medium 10 (10A).
