PPROBLEM TO BE SOLVED: To improve an operation response in relation to a user by reducing power consumption and suppressing decrease of battery residual quantity when mounting an HDD and a buffer memory. PSOLUTION: A memory area of a buffer memory which temporarily stores data written in the HDD is managed by clearly dividing into a buffer memory area for sequential data, such as audio data and that for random access data, such as an address book. For the random access data, the number of accesses to the HDD at the time of using the random access data use is reduced by normally storing the data in the buffer memory area for the random access data.
