1. An information processing apparatus, comprising:
- a controller configured to read data by outputting, to a storage device having a data-recordable medium, a request for reading data recorded to the medium;
whereinusing file system management information corresponding to the data recorded to the medium, the controller generates, and outputs to the storage device, bit map data enabling the storage device to distinguish between the first cluster numbers where the starting data of read files are recorded, and the first cluster numbers where the starting data of non-read files are recorded.

Abstract
An information processing apparatus includes a controller that reads data by outputting, to a storage device having a data-recordable medium, a request for reading data recorded to the medium. Using file system management information corresponding to the data recorded to the medium, the controller generates, and outputs to the storage device, bit map data enabling the storage device to distinguish between the first cluster numbers where the starting data of read files are recorded, and the first cluster numbers where the starting data of non-read files are recorded.

6. A storage device, comprising:
-
a medium upon which data is recorded; and a controller configured to write or read data with respect to the medium; wherein the controller receives, from a host, bit map data enabling the controller to distinguish between the first cluster numbers where the starting data of read files requested by the host are recorded, and the first cluster numbers where the starting data of non-read files are recorded, and the controller reads files by applying the received bit map data and file system management information to analyze the clusters where the read files are recorded.

7. An information processing system, comprising:
-
a host configured to use file system management information corresponding to data recorded to a medium to thereby generate, and output to a storage device, bit map data enabling the storage device to distinguish between the first cluster numbers where the starting data of read files are recorded, and the first cluster numbers where the starting data of non-read files are recorded; and a storage device configured to receive the bit map data from the host, and read files by applying the received bit map data and file system management information to analyze the clusters where the read files are recorded.

8. An information processing method executed in an information processing apparatus, comprising the steps of:
-
using file system management information corresponding to data recorded to a medium to thereby generate, and output to a storage device, bit map data enabling the storage device to distinguish between the first cluster numbers where the starting data of read files are recorded, and the first cluster numbers where the starting data of non-read files are recorded; outputting a request read data recorded to the medium to the storage device; and sequentially receiving from the storage device all data for the read files identified by the bit map data.

9. A program causing information processing to be executed in an information processing apparatus, comprising the steps of:
-
using file system management information corresponding to data recorded to a medium to thereby generate, and output to a storage device, bit map data enabling the storage device to distinguish between the first cluster numbers where the starting data of read files are recorded, and the first cluster numbers where the starting data of non-read files are recorded; outputting a request read data recorded to the medium to the storage device; and sequentially receiving from the storage device all data for the read files identified by the bit map data.
