Abstract
The simplified high-speed memory control and simplified flexible memory management are provided for an information recording/reproducing device having a recording medium having an erasure unit larger than the writing unit. A recording medium 3 is such a recording medium having an erasure unit larger than a writing unit, such as a flash memory. When recording data of a file transferred via a transfer control section 5 on a recording medium 3, a recording medium controller 2 records data beginning from the leading position of the erasure unit. Moreover, only data of a given file is recorded in one erasure unit, so that data of another file is not allowed to co-exist in one erasure unit. When re-writing file data, pre-existing files can be erased in a lump without retreating to, for example, an external buffer, thus assuring facilitated memory management, such as readout of file data.
