Abstract

A data recording/reproduction apparatus classifies each request into any one of a real-time processing data request, a metadata request, and a non-real-time data request and accumulates each classified request. A request readout device in the apparatus sequentially reads out each accumulated input/output request in accordance with a predetermined reference time. In order to attain a desired data rate of the real-time processing data, the request readout device delays reading out a metadata request for a fixed period specified by the reference time. A processing of delayed metadata input/output request collectively is executed with a subsequent processing metadata input/output request.
