A part of the data stored in a disk D is stored in an HDD (420) having a reading speed for reading the stored data and outputting them higher than the reading speed of a data reading section (410) for reading the data recorded in the disk D and outputting them. When a request information requesting distribution of the data is recognized, a content distributor (430) and content administrator (440) cause the HDD (420) to read and output the part of the data, while they cause the data reading section (410) to read and output the remaining part of the data recorded in the disk D.
