ABSTRACT:
The present invention relates to video recording and playback techniques and devices which create relative movement between a laser and an optical medium such as a flexible optical tape to permit recording of relatively high bandwidth signals. Further, the present invention relates to video recording and playback techniques and devices which optimize relative movement between a laser source and the optical medium in a cost-effective manner. Data spots having a set of predetermined feature sizes (i.e., set of varying hole sizes) can thus be recorded at a rate useful for high bandwidth signals (e.g., television video signals). Further, recording on a flexible optical medium (e.g., optical tape) can be performed in a manner which optimizes space efficiency on the tape.
