Abstract

PURPOSE:To attain a speedy and exact access even in case of a card type optical recording medium by also providing a preamble and a post-amble to the track number part of area for a track between the parallel reference lines of a card type substrate. CONSTITUTION:An area 3 for a data track, which is put between respectively parallel reference lines 4, is provided to the recording area of the card type substrate. A track number part TN, which succeeds to a leading-in part L1 of this area 3, forms a track number C with a preamble part B and a post- amble part E which are preceding and succeeding this number C and a desired track number is exactly read without fail by an optical head. As the result, even in case of the card type optical recording medium, the speedy and exact access can be executed.
