Abstract

광헤드(21)와 함께 테이프(13)의 또는 이로부터 정보 기억 및 재생을 위한 시스템이다. 테이프(13)는 두릴 허브(18,19)상에 권취되며 릴 허브 사이에서 안내면(32)에 의해 안내된다. 안내면(32)은 헤드(21)가 테이프(13)와 협동하는 위치에서 테이프(13)를 위치결정한다. 최소 액세스 시간을 얻기 위해 안내면(32)은 테이프(13)와 안내면(32)간의 마찰을 최소화하기 위해 치수결정된다.Together with the optical head 21 is a system for storing and reproducing information on or from the tape 13. The tape 13 is wound on the reel hubs 18, 19 and guided by the guide surface 32 between the reel hubs. The guide surface 32 positions the tape 13 at a position where the head 21 cooperates with the tape 13. Guide surface 32 is dimensioned to minimize friction between tape 13 and guide surface 32 to obtain the minimum access time.
