a mounting information storage area that stores mounting information and a cache; and
a master boot record that stores a starting location and an area size of a drive area,
wherein the mounting information is usable for a mounting process of the recording medium by the drive device, the mounting information being management information that is used by the drive device to mount drive areas for storing actual data, and
wherein the cache includes file allocation information, entry information and task information, the cache stored to the mounting information storage area after the mounting information is stored to the mounting information storage area when the drive device is set to a specific state.
2. The recording medium according to claim 1 , wherein the specific state is a mounting process for reading the specific file set by a user and setting a specific state, such as a pause or a suspension after the normal mounting, the specific file includes, for example, information of one or more generations including information of one or more drives, directories, or files that are most recently accessed.
3. The recording medium according to claim 1 , wherein the mounting information is preferentially read in the mounting process.
4. The recording medium according to claim 1 , wherein the mounting information includes a number of drives to be mounted and a mounting start location.
5. The recording medium according to claim 1 , wherein a type of the mounting process executed in accordance with the mounting information includes a normal mounting process and a specific state mounting process, the specific state mounting process including a specific process which is performed after the normal mounting process.
6. A drive device connectable to a recording medium comprising:
a memory that stores drive information related to data storage to the recording medium;
an extractor that extracts mounting information out of the drive information, the mounting information being management information that is used by the drive device to mount drive areas for storing actual data;
a writer that writes the extracted mounting information into a mounting information storage area; and
a mounting processor that executes a mounting process of the recording medium based on the mounting information,
wherein the writer writes to a cache stored in the mounting information storage area after the mounting information is written to the mounting information storage area when the drive device is set to a specific state, the cache including file allocation information, entry information and task information.
7. The device drive according to claim 6 , wherein the mounting information storage area stores the mounting information used in the mounting process.
8. The drive device according to claim 6 , wherein the extractor extracts information used in the mounting process of the recording medium from the drive information stored in the memory as mounting information after a specific file is written into the mounting information storage area.
9. The drive device according to claim 6 , wherein, when a specific file including information concerning at least one of an accessed drive, an accessed directory, and a file is loaded after the mounting process, the writer stores the specific file after the mounting information being stored in the mounting information storage area.
10. The drive device according to claim 9 , wherein the accessed drive, the accessed directory or the accessed file stored is that which was most recently accessed.
11. The drive device according to claim 6 , comprising:
a first detector that detects a connection of the recording medium, and
wherein the extractor extracts information used in the mounting process of the recording medium from the drive information stored in the memory as mounting information when a connection of the recording medium is detected.
12. The drive device according to claim 6 , comprising:
a second detector that detects an activation of the drive device, and
wherein the extractor extracts information used in the mounting process of the recording medium from the drive information stored in the memory as mounting information when an activation of the drive device is detected.
13. The drive device according to claim 6 , comprising:
a detector that detects a stoppage of the drive device, and
wherein the extractor extracts information used in the mounting process of the recording medium from the drive information stored in the memory as mounting information when a stoppage of the drive device is detected.
14. The drive device according to claim 6 , wherein the writer writes the mounting information stored in the mounting information storage area into the memory when an execution instruction of the mounting process is received, and the mounting processor generates drive information based on the mounting information.
15. The drive device according to claim 14 , wherein the mounting processor repeatedly executes the mounting process for each drive area.
16. A mounting method to make a recording medium usable, the mounting method comprising:
extracting, using a computer, mounting information used in a mounting process of the recording medium out of drive information stored in a memory, the mounting information is management information that is used by a drive device to mount drive areas for storing actual data;
writing the extracted mounting information into a mounting information storage area of the recording medium;
executing a mounting process of the recording medium based on the mounting information written into the mounting information storage area;
storing the mounting information to the mounting information storage area at a timing of reading or writing of a file operation; and
storing data in a cache of the mounting information storage area after the mounting information is stored to the mounting information storage area when the drive device is set to a specific state, the data including file allocation information, entry information and task information.
17. The mounting method according to claim 16 , wherein the mounting information stored in the mounting information storage area is stored in the memory when an execution instruction of the mounting process of the recording medium is received, and the stored mounting information is used to generate the drive information.
18. The mounting method according to claim 16 , wherein a computer with the memory, coupled to the recording medium, executes the mounting process.
