Abstract
There is disclosed an information reproducing apparatus and an information recording apparatus in which information transfer is possible by an information amount unit different from a sector unit, so that a burden on a host apparatus is lightened, waste of transfer time is avoided, and information protection level is raised. In a magnetooptic disk drive which serves as both the information reproducing apparatus and the information recording apparatus, non-sector unit information is designated as reproducing information, information for the integer number of sectors including the non-sector unit information is reproduced from a magnetooptic disk , and only the non-sector unit information is outputted to a host computer . Moreover, the non-sector unit information is received as recording information from the host computer , the information for the integer number of sectors is reproduced from the integer number of sectors including an area in which the non-sector unit information is to be recorded, a part of the information for the integer number of sectors is replaced with the non-sector unit information, and the partially replaced information for the integer number of sectors is recorded in the magnetooptic disk
