Patent ID: 8250087

Claim:
An information processing apparatus, comprising: a controller configured to read data by outputting, to a storage device having a non-transitory data-recordable medium, a request for reading data recorded to the non-transitory data-recordable medium; wherein using file system management information corresponding to the data recorded to the non-transitory data-recordable medium, the controller generates, and outputs to the storage device, bit map data enabling the storage device to distinguish between first cluster numbers where a starting data of read files are recorded, and first cluster numbers where a starting data of non-read files are recorded, the bit map data including respective bits for respective first cluster numbers in a first cluster number list for recorded files, the first cluster number list for recorded files being a list containing the first cluster number for each file recorded to the non-transitory data-recordable medium, and the respective bit for each first cluster number indicating whether or not the first cluster number corresponds to a file that is to be read from the non-transitory data-recordable medium.
