To provide "an electronic apparatus" which attains efficient use of a cache memory for storing information read out from a hard disk while shortening seek time when reading the information from the hard disk, at start-up.

When the electronic apparatus 100 is started, a control part 102 reads at least AV data stored on the outer peripheral side of the hard disk 108 and required to start the electronic apparatus 100 or map data stored on the inner peripheral side and required to start the electronic apparatus 100 all together on the basis of AV data statistic information and map data statistic information, and stores it in the cache memory 105. The control part 102 reads at least the AV data or the map data required to start the electronic apparatus 100 from the cache memory 105 and processes it.
