Abstract

본 발명은 이색성 염로로 구성된 호메오트로픽하게 배항된 액체 결정성 중합체 필름에 관한 것으로 이색성 염료의 존재를 따른 상기 호메오트로픽 배향은 데이타를 라이팅하는 것과 리딩하는 상이한 기술을 선택하는 것을 가능하게 하며, 상기 경우에 콘트라스트가 액체 결정성 중합체의 메소겐 그룹과 동일한 방향으로 배열되는 필름내 함유된 이색성 염료에 의해서 얻어지며, 원 필름에서 메소겐 그룹 및 이색성 염료 분자들은 필름의 표면에 수직으로 배향되고 상기 분자들에 의한 입사광의 낮은 흡수만이 있을 뿐이며 필름을 국부적으로 가열하거나 조사함에 의해 호메오트로픽 배향이 이소트로픽 배향으로 전환되고, 이소트로픽하게 라이팅된 흔적의 경우에 이색성 염료는 반사광의 보다 높은 흡수를 야기하면서, 마찬자지로 이소트로픽하게 배향되는 것을 특징으로 한다.
