Abstract
This invention discloses an optical data access system. The optical data access system includes an optical flat data storage medium. The optical data access system further includes a data access drive system for driving an optical pickup head for performing a rotational movement over the flat data storage medium for accessing data over an arc segment on the optical flat data storage medium. And, the optical data access system further including a controller for controlling a data transfer between the data access drive system and the optical flat data storage medium. In a preferred embodiment, the optical flat data storage medium is an optical data card. In a different preferred embodiment, an optical pickup head is provided for accessing data over substantially one-half of the rotational movement.
