Information reproducing element, information reproducing head comprising same, information reproducing apparatus, and information reproducing method

摘要

An information reproducing element formed by a plurality of transferring portions sandwiching magnetically insulatable regions is arranged so as to face an information recording medium. A plurality of record marks on the information recording medium are mutually insulatedly transferred onto the information reproducing element. A light beam is irradiated onto the information reproducing element. The record marks recorded by high density recording are then reproduced by magneto-optical reproduction or maximum-likelihood detection.
