[Table 2]

Main Configuration of System Controller Next, returning to FIG. 1, the buffer memory 34A of the system controller 34 is a memory for temporarily storing the information read from the disk 12. The access information processing unit 34B is for processing the access information as described later and calculating the rental fee when the main information of the disk 12 is accessed. The operation mode determination unit 34C includes the key unit 42 and the I / F 4
It is for determining the operation mode by referring to the input signals from the respective 4's. For example, normally, it is determined to be the user mode, and when there is a preset key input, it is determined to be the shop mode.

Configuration of Host Side Next, a host side management apparatus installed in a disk rental shop or the like will be described. This management device
The disk drive device 10 is combined with a host computer 50 composed of a personal computer or the like, and the host computer 50 is connected to the I / F 44 provided in the disk drive device 10. ing. The whole of FIG. 1 may be integrated.

The host computer 50 has an access information editing section 50A for editing various information such as a customer code for the access information, a host memory 50B for accumulating the access information of each customer, and an input key section 50C. It is provided.

<Operation When Used by User> Next, the operation of the disk drive device will be described with reference to the flowchart of FIG. The user rents the disk at the rental shop and sets it in the disk drive device 10 (step S1). Next, when the drive section is instructed by the key section 42 (step S2), the operation mode determination section 34C of the system controller 34 determines that the mode is the user mode, and the following operation in the user mode is performed.

First, as described above, the disk 12 rotates at CLV, and the transducer 16 moves to the inner peripheral side to move the TOC area 12A and the first UTOC area 1 to each other.
2B (see FIG. 2) (step S3).

On the one hand, the types of the information in the TOC area 12A and the UTOC area 12B, particularly the table of contents information, are checked by the access information processing section 34B (step S).
3). Then, the contents of the table of contents are displayed on the display device 40 (step S4). FIG. 4 shows an example of the display. According to this, the set disc 12
It can be seen that the book contains the first to third volumes of Dan Ikuma's "Pipe's Smoke", as well as Picasso's paintings, Beethoven's sheet music and other main information.

Next, the user operates the key portion 42 while referring to the table of contents to select and instruct desired main information (step S5). Then, the transducer 16 moves to the corresponding address (step S6), and the main information selected by the user is read from the disk 12 and stored in the buffer memory 34A (step S7). next,
The transducer 16 moves to the second UTOC area 12C (step S8), and when the access information is recorded, reads it and outputs it to the access information processing unit 34B (step S9).

The access information processing section 34B checks the input access information and confirms the access date, time,
Information on the number of times, continuity, and the number of pages accessed is updated, and an access fee is calculated from the type of main information (step S10). The access information is recorded in the second UTOC area 12C of the disk 12 by the recording head 14 and the transducer 16 (step S11).

More specifically, if the current access is the first access after renting the disk 12, the access information of the user does not exist in the second UTOC area 12C of the disk 12, so The access information is recorded as it is in the second UTOC area 12C (step S11). At this time, a table of contents (directory) for access information is set corresponding to the table of contents of the main information.

If you have already accessed after renting,
Since the previous access information is recorded in the second UTOC area 12C, this is checked by the access information processing unit 34B. For example, the last access was from page 1 to page 4 of "Smoke of Pipe 1" by Dan Ikuma,
Suppose you accessed pages 4 to 10 this time. The access information processing unit 34B determines that the access is continuous from the previous access page and the current access page. Also, the number of unique pages accessed is determined.

By the continuity, novels,
You can judge whether you watched music, movies, etc. as a sample or watched continuously for a certain length. Also, for poetry, paintings, encyclopedias, etc. that have little or no continuity, the access information of this time is used as it is regardless of the access status of the past.

The access fee is calculated as follows, for example. In the case of main information such as a novel that is accessed continuously and is meaningful, if it is accessed continuously, it is calculated as 1 page × × yen, and if it is discontinuous, it is viewed as a sample Don't charge for things. Since paintings and the like have meaning on each screen, they are added for each screen regardless of whether they are continuous or discontinuous.

After the processing of the access information as described above, the main information stored in the buffer memory 34A is output to the display device 40 and displayed (step S1).
2). When the user sees this display and determines that external output, for example, printout is necessary, the I / F 4
A printer is connected to No. 4, and a key input to that effect is made by the key unit 42 (step S13).

Then, that effect is first transmitted to the access information processing section 34B, the transducer 16 moves,
The access information "external output" is the second UTOC area 1
The fee for external output is calculated and recorded in the corresponding portion of 2C (steps S14, S1).
5). Then, the system controller 34 outputs the relevant main information from the I / F 44 to the outside (step S16).

Although not shown in FIG. 3, when page turning is instructed by a key operation, the above-described processing is performed on the access information and the corresponding page is displayed. Then, when accessing other main information, the user gives an instruction to display the table of contents (step S1).
7). Then, the above-described operations after step S4 are repeated. If no display is made, the process ends.

As described above, in the disk drive device 10, the main information of the disk 12 accessed by the user is temporarily stored in the buffer memory 34A, the access information is processed and written in the second UTOC area 12C of the disk 12, Main information is displayed and output. Disk drive device 1
When the power of 0 is turned off, it is impossible to record the access information on the disc. Therefore, at least the recording of the access information is started before the main information is displayed and output. This prevents the inconvenience that the fee for the main information accessed due to lack of access information cannot be charged.

<Operation on Rental Shop Side> Next, the operation on the management apparatus side when the disk used by the user is returned to the rental shop as described above will be described with reference to the flowchart of FIG. First, the disk 12 is set in the disk drive device 10 (step S20). The rental shop side gives an instruction to start driving with the key unit 42 or 40C (step S21) and performs a predetermined key operation. Then, the operation mode determination unit 34C of the system controller 34 determines that the operation mode is the shop mode, and the following operation in the shop mode is performed (step S22). When this key operation is not performed, the operation in the user mode of FIG. 3 described above is performed (step S23).

When it is determined that the mode is the shop mode, the system controller 34 causes the disk 12 TO
C area 12A, first UTOC 12B, and second UTOC
The transducer 16 sequentially moves to the area 12C (step S24), and the recorded contents are read out and stored in the buffer memory 34A (step S25).
The recorded contents are displayed on the display device 40 (step S26).

FIG. 6 shows an example of the display. As described above, in the shop mode, the access information is displayed in addition to the table of contents of the main information of the disc 12. In the example shown, the novel in Table of Contents 1 has 20 consecutive days on July 18.
There is an access to the page and there is also an external output, so the access charge is 40 yen. Next, the painting in Table of Contents 4 had two pages of discontinuous access on July 12, and the charge was 100 yen. Next, the encyclopedia in Table of Contents 6 had discontinuous and overlapping accesses on July 17, resulting in 48 accesses and 35 pages. And the charge is 48 yen. The same applies hereinafter.

In the host computer 50, the access information editing unit 50A calculates the rental fee in consideration of the access fee and edits the user code and the like if necessary (step S28). Then, the screen display is as shown in FIG. 6B (step S29). Based on this display, the rental shop charges the user a rental fee. In addition, the edited access information is printed out as a usage statement in accordance with the operation instruction of the key unit 50C, and further stored in the host memory 50B for subsequent user management. This host memory 50B
By statistically processing the contents of, it is possible to know good customers and popular products.

Thereafter, when the deletion of the access information is instructed by the key unit 42 or 50C (step S30),
The access information of the second UTOC area 12C is erased (step S31). As a result, the disk 12 can be rented again.

<Effects of the Embodiment> As described above, according to the present embodiment, the usage condition such as the usage content and the usage frequency can be changed from the method such as a conventional rental CD for how much each one day is used. You can charge how much you want, and you can rent at a reasonable price. In other words, various kinds of information can be rented in addition to music and movies. In particular, when one image such as a painting, a musical score, or a photograph is related to copyright, or in the case of a large file such as an encyclopedia, it is possible to determine a charge according to the information. In addition, by accumulating the access information, it is possible to easily manage the usage status.

<Use as Electronic Lending Book> Next, an embodiment in which the present invention is used for electronic lending in a library will be described with reference to FIG. At the time of lending, the lending information such as lending date, lending destination, and return deadline is stored in the second UTOC area of the disk to be lent or the host memory 60C of the host device by the lending processing unit A of the host device 60 on the library side. Will be recorded. When the user accesses the disc, the access information is recorded in the same manner as in the above embodiment.

When the disc is returned to the library, the return processing unit 60B of the host device 60 performs return processing such as checking the return date. By accumulating such lending / returning information in the host memory 60C and statistically processing it, the frequency of use of electronic books, the return status, etc. can be grasped.
