摘要：
A run length limited code recording/reproduction apparatus according to an aspect of this invention includes a generation unit for generating a plurality of different code sequences which have recording densities that gradually become higher, and a recording unit for recording the plurality of different code sequences generated by the generation unit on a plurality of successive subfields in a test data field of an information storage medium.
