In a disc apparatus, past access records concerning data items stored in the optical disc apparatus and exchange records of optical discs are managed, and access frequencies in the future are estimated on the basis of these records. Data items estimated to be accessed at a high frequency are stored into a cash HDD as a high-speed device, and data items estimated to be accessed at a middle frequency are collected into a specific optical disc. This specific optical disc is continuously installed in an optical disc drive. As a result, the response ability of the apparatus is greatly improved.
