Abstract
When an object file is read from a recording medium by a file system, a jump table retrieving section retrieves a unit-record-area number, corresponding to the unit record area to which individual desired data of the object file is allocated or a unit-record-area number near individual desired data, from a jump table corresponding to the object file. And a unit record area retrieving section retrieves a unit record area containing the individual desired data by referring a file allocation table based on the retrieved unit-record-area number. Then an accessing section takes access to the recording medium to read out the individual data recorded in the unit record area. This system realizes high-speed retrieving of intended unit record areas when writing/reading a file to/from the recording medium.
