a first external storage device, for which access speed is slower than the storage unit; and
a second external storage device, for which access speed is slower than the first external storage device, and
the content management unit determines, when moving the content data saved in the storage unit to one of the first external storage device or the second external storage device, whether or not the content data is saved in the other one of the first or the second external storage device based on the storage area information of the management information, and deletes the content data from the storage unit after copying the content data from the storage unit to the other one of the first or the second external storage device if the content data is not saved.
2. The information processing apparatus according to claim 1 , wherein
the management information further includes last access time and date information representing a last access time and date with respect to the content data by the information processing apparatus, and
the content management unit obtains an elapsed time from the last access time and date with respect the content data based on the last access time and date information, and manages the storage area of the content data according to the elapsed time.
3. The information processing apparatus according to claim 2 , wherein
the external storage device includes a first external storage device, which access speed is slower than the storage unit, and
the content management unit copies or moves the content data from the storage unit to the first external storage device when the elapsed time from the last access time and date with respect to the content data saved in the storage unit is greater than or equal to a predetermined first threshold value.
4. The information processing apparatus according to claim 3 , wherein
the external storage device includes the first external storage device and a second external storage device, which access speed is slower than the first external storage device; and
the content management unit copies or moves the content data from the storage unit or the first external storage device to the second external storage device when the elapsed time from the last access time and date with respect to the content data saved in the storage unit or the first external storage device is greater than or equal to a predetermined second threshold value greater than the first threshold value.
5. The information processing apparatus according to claim 4 , wherein
the second external storage device includes a drive for recording data to a removable medium attached to the second external storage device, and
the content management unit moves the content data from the storage unit, the first external storage device, or the second external storage device to the removable medium attached to the second external storage device or deletes the content data when the elapsed time from the last access time and date with respect to the content data saved in the storage unit, the first external storage device, or the second external storage device is greater than or equal to a predetermined third threshold value greater than the second threshold value or when a free space of the second external storage device is smaller than or equal to a predetermined value.
6. The information processing apparatus according to claim 1 , wherein when accepting a reproducing instruction on content data saved in the external storage device, the content management unit acquires the content data, which reproducing instruction is accepted, from the external storage device through the communication unit with the reproducing instruction as a trigger, and saves the content data in the storage unit.
7. A content management method, comprising the steps of:
receiving, by a content management unit of an information processing apparatus communicable with one or more external storage devices, a notification indicating that new content data is saved in the external storage device from the external storage device;
acquiring the new content data from the external storage device with the notification as a trigger, and saving the new content data in a storage unit of the information processing apparatus by the information processing apparatus; and
storing, in a management information storage unit of the information processing apparatus, management information including storage area information of content data saved in at least one of the storage unit or the external storage device; wherein the content management unit manages a storage area of the content data in the storage unit and the external storage device based on the management information stored in the management information storage unit;
wherein the external storage device includes:
a first external storage device, which access speed is slower than the storage unit; and
a second external storage device, which access speed is slower than the first external storage device, and
the content management unit determines, when moving the content data saved in the storage unit to one of the first external storage device or the second external storage device, whether or not the content data is saved in the other one of the first or the second external storage device based on the storage area information of the management information, and deletes the content data from the storage unit after copying the content data from the storage unit to the other one of the first or the second external storage device if the content data is not saved.
8. A non-transitory recording medium storing a program for causing an information processing apparatus communicable with one or more external storage devices to execute the steps of:
receiving, by a content management unit of the information processing apparatus, from the external storage device, a notification indicating that new content data is saved in the external storage device;
acquiring the new content data from the external storage device with the notification as a trigger, and saving the new content data in a storage unit of the information processing apparatus; and
storing, in a management information storage unit of the information processing apparatus, management information including storage area information of content data saved in at least one of the storage unit or the external storage device; wherein the content management unit manages a storage area of the content data in the storage unit and the external storage device based on the management information stored in the management information storage unit;
