Optical Information Recording Medium and Optical Apparatus for Reproducing Information Therefrom Abstract The invention pertains to a card-shaped optical information recording medium and an optical apparatus for reproducing information from said medium. The card-shaped optical recording medium contains starting position row and information rows comprising reference marks for auto-tracking, auto-focusing and row addressing, and data sub-rows. Optical information recorded in rows on said medium is read by said apparatus one row at a time through an optical imaging system and 1-D detector array. By 1-D scanning row by row, tracking mechanism is simplified and data transfer rate is greatly increased.
