An information processing apparatus for recording data onto a recording medium, includes an access controller for outputting, to a medium-specific controller, record data input from an application and directed to the recording medium. The access controller performs a read-modify-write (RMW) operation by verifying whether one of a record start position and a record end position of the record data input by a logical sector unit from the application is different from a delimitation position of a physical sector as an access unit of the recording medium, acquiring the record data by the physical sector unit and storing the record data onto a memory if one of the record start position and the record end position is different from the delimitation position, updating logical sector data as part of stored physical sector data with the input record data, and outputting the updated physical sector data to the medium-specific controller.
