[0053]
Next, the operation of the information distribution apparatus according to the present embodiment will be described with reference to FIGS.
[0054]
First, the data storage step will be described with reference to FIG.
[0055]
In FIG. 2, first, data including moving image data, still image data, audio data, text data, and the like, and data of a distribution schedule for distributing the content are downloaded from the information management center by the data input unit 11 and input. (Step S21). When a plurality of data are packaged and input, the data input unit 11 expands the package and acquires each data. Next, the data write / read management unit 16a determines whether or not the data size of the input data is equal to or larger than a predetermined threshold (step S22).
[0056]
If it is determined in step S22 that the data size of the input data is equal to or larger than the threshold value, the data storage position setting unit 16b causes the track stored on the magnetic disk 15d to be closer to the outer circumference than a predetermined track on the magnetic disk 15d. It is set (step S23). On the other hand, if it is determined in step S22 that the data size of the input data is not equal to or larger than the threshold value, the data storage position setting unit 16b causes the track stored on the magnetic disk 15d to be larger than the predetermined track on the magnetic disk 15d. It is set on the inner circumference side (step S24).
[0057]
Here, the storage position of the magnetic disk 15d set by the data storage position setting unit 16b will be described with reference to FIG.
[0058]
In FIG. 3, a predetermined reference track 31 is shown on the magnetic disk 15d.

[0059]
On the other hand, in the above-described step S22, the track in which the data whose input data size is not determined to be equal to or larger than the threshold is stored by the data storage position setting unit 16b, For example, it is set to the track 33.
[0060]
Here, assuming that the diameter of the magnetic disk 15d in the HDD is 3.5 inches and the number of rotations is 5400 rpm, the transfer rate is 287 Mbps for the outermost track and 142 Mbps for the innermost track. Further, the number of continuous sectors increases along the direction from the inner circumference to the outer circumference, and is 1550 for the outermost track and 770 for the innermost track. The storage capacity of the outermost track is 775 kB, and that of the innermost track is 385 kB.
[0061]
That is, since the continuity of data increases from the inner circumference to the outer circumference, the data access time of the magnetic head 15c can be reduced on the outer circumference side than on the inner circumference side. Also, when data storage and erasure are repeated, a phenomenon occurs in which data is dispersed and stored on the disk due to the characteristics of the HDD at the time of data storage. In the present embodiment, however, the data size is equal to or larger than the threshold. Is always stored on the outer peripheral side, the discontinuity of data is reduced, and the data access time of the magnetic head 15c can be reduced.
[0062]
Therefore, by comparing the data size of the input data with a threshold value and setting a storage track to store, for example, data of 40 MB or more on the outer peripheral side, data of a large data size can be continuously stored. Moreover, data can be read at high speed.
[0063]
Subsequently, the information set by the data storage position setting unit 16b is output to the magnetic storage device 15 by the data write / read management unit 16a, and the data is written to a predetermined track by the magnetic head 15c (step S25).
[0064]
Next, a data reproducing step will be described with reference to FIG. Note that this reproduction step is processed in parallel with the data storage step described above.

The data of the distribution schedule includes a data list that lists a time at which the content is distributed and data of the content to be distributed.
[0066]
Subsequently, the information of the data list of the listed contents is output to the magnetic storage device 15 by the data write / read management unit 16a, and the data of the contents stored in the magnetic disk 15d is sequentially read by the magnetic head 15c ( Step S27). Then, the data of the content is distributed to, for example, the video terminal device by the data distribution unit 17 (step S28).
[0067]
The magnetic storage device 15 is not limited to an HDD, but may be, for example, a magneto-optical storage device, a DVD-RAM, or the like. Further, the magnetic storage device 15 may include a magnetic storage device management unit 16.

[0071]
As described above, according to the information distribution device 10 of the present embodiment, the data storage position setting unit 16b sets the track position for storing data on the magnetic disk 15d according to the data capacity of input data. Therefore, for example, data of a content having a large data size, such as moving image data, can be stored in an outer track while being downloaded, and the data of the stored content can be read at the same time. However, the content can be distributed without interruption.
[0072]
(Second embodiment)
[0073]
First, the configuration of the information distribution device according to the second embodiment of the present invention will be described.
[0074]

Therefore, the description of the same configuration as the configuration of the information distribution device 10 of the first embodiment is omitted.
[0075]
The storage area dividing unit 16c divides the storage area of the magnetic disk 15d into a plurality of storage areas. Further, the storage capacity changing unit 16d can acquire and change the storage capacity of the storage area divided by the storage area dividing unit 16c. The data write / read management unit 16a can identify the type of input data. The storage area dividing unit 16c and the storage capacity changing unit 16d constitute a storage area dividing unit and a storage capacity changing unit, respectively.
[0076]
Next, the operation of the information distribution device 50 of the present embodiment will be described. Note that the data reproduction step of the information distribution device 50 is the same as the operation of the information distribution device 10 of the first embodiment, and thus the description is omitted, and the data storage step is described with reference to FIGS. 7 and 8. explain.
[0077]
In FIG. 7, first, the storage area of the magnetic disk 15d is divided into a plurality of storage areas by the storage area dividing unit 16c (step S61). For example, as shown in FIG. 8, the storage area dividing unit 16c allows the storage area of the magnetic disk 15d to have a first storage area 71 for storing moving image data and a second storage area for storing still image data. It is divided into an area 72 and a third storage area 73 for storing data other than moving image data and still image data. The capacity of each storage area is, for example, when the total storage capacity is 70 GB, the capacity of the first storage area 71 is 40 GB, the capacity of the second storage area 72 is 20 GB, and the capacity of the third storage area 73 is Should be allocated to 10 GB.
[0078]
Subsequently, the data input unit 11 downloads and inputs contents including moving image data, still image data, audio data, text data, and the like, and data of a distribution schedule for distributing the contents from the information management center (step S62). ). Next, the data writing / reading management unit 16a determines whether or not the input data is moving image data (step S63). For example, the data write / read management unit 16a identifies the extension of the file containing the data, and determines whether or not the file is moving image data.
[0079]
If it is determined in step S63 that the input data is moving image data, the storage capacity of the first storage area 71 for storing moving image data is acquired by the storage capacity changing unit 16d (step S64). ). Further, the storage capacity changing unit 16d determines whether the storage capacity of the first storage area 71 for storing moving image data is insufficient (step S65).
[0080]
If it is determined in step S65 that the storage capacity of the first storage area 71 for storing moving image data is insufficient, the storage capacity of the first storage area 71 is expanded by the storage capacity changing unit 16d. (Step S66), the storage capacity is increased. For example, when the data size of the input moving image data is 2 GB and the free space of the first storage area 71 for storing moving image data is 1 GB, the storage capacity changing unit 16d sets the second storage area 72 Is reduced, and the free space of the first storage area 71 is increased to, for example, 3 GB.
[0081]
Subsequently, the moving image data is written into the first storage area 71 by the magnetic head 15c (step S67). If it is not determined in step S65 that the storage capacity of the first storage area 71 for storing moving image data is insufficient, the process proceeds to step S67.
[0082]
If the input data is not determined to be moving image data in step S63 described above, the input data is stored in the storage area on the inner peripheral side of the first storage area 71 by the magnetic head 15c. For example, in the case of still image data, it is stored in the second storage area 72, and in the case of text data, it is stored in the third storage area 73.
[0083]
The management information for managing the data name, data size, storage location, storage date and time, etc. of the data stored on the magnetic disk 15d is frequently accessed by the magnetic head 15c and is written and read. A storage area may be provided outside the first storage area 71 to store the management information so that the management information can be accessed in a short time.
[0084]
Further, the transmitting device of the information management center 41 shown in FIG. 5 described above identifies the data based on the type of the data, for example, by adding an extension corresponding to the type of the data, and sends the information to the information distribution device 10. It may be configured to transmit.
[0085]
As described above, according to the information distribution apparatus 50 of the present embodiment, the storage area dividing unit 16c divides the storage area of the magnetic disk 15d into a plurality of storage areas, and the storage capacity changing unit 16d Since the storage capacity of the storage area divided by the division unit 16c is obtained and changed, for example, data of a content having a large data size such as moving image data is downloaded to a track of the storage area on the outer peripheral side while downloading. At the same time as the storage, the data of the stored content can be read, and the content can be distributed without interruption even if the data size is large.
[0086]
