Patent ID: 8159766

Claim:
An information-processing apparatus, comprising: a processing unit that compresses inputted data from a first storage medium to produce first compressed data of a first compressed format; a storage unit that stores the first compressed data in a second storage medium, the second storage medium also configured to store second compressed data of a second compressed format; and a reading-out unit that reads-out data from the first storage medium at a predetermined read-out data rate to produce the inputted data, the processing unit further configured to control the storage unit to write the first compressed data in the second storage medium at a faster writing data rate than the predetermined read-out data rate, wherein the processing unit decompresses the second compressed data, stored in the second storage medium, of the second compressed format to produce decompressed data, and the processing unit is configured to control the storage unit to store the first compressed data of the first compressed format in the second storage medium while the processing unit simultaneously decompresses the second compressed data, stored in the second storage medium, of the second compressed format and audibly reproduces the decompressed data, the first compressed format being different than the second compressed format.
