Embodiment approach 1

[0027] Below, according to Figure 1 to Figure 4 A first embodiment of the present invention will be described.

[0028] (Structure of Optical Disc Device 1)

[0029] figure 1 It is a block diagram showing the configuration of the optical disc device (information processing device) 1 according to this embodiment. The optical disc device 1 includes a main body 2 , a display 3 and an input device 4 . The display 3 displays images based on the image data output from the main body 2 via the image output unit 7 , for example, a liquid crystal display can be preferably used. The input device 4 is a device for the user to give an input instruction to the main body 2 via the I / O control unit 8 , for example, a keyboard or a mouse is used.

[0030] The main body 2 includes a Blu-ray Disc (BD) drive 5 and an arithmetic processing unit 6 . The BD drive 5 has a function of reading information from a hybrid optical disc (optical recording medium) 10 inserted into the main body 2 or re...

Embodiment approach 2

[0044] Below, according to Figure 5 and Figure 6 A second embodiment of the present invention will be described. In addition, for convenience of description, components having the same functions as those described in Embodiment 1 are denoted by the same reference numerals and descriptions thereof are omitted.

[0045] (Structure of Optical Disc Device 1a)

[0046] Figure 5 It is a block diagram showing the structure of the optical disc device 1a of this embodiment. The optical disc device 1 includes a main body 2 a , a display 3 and an input device 4 . The main body 2 a includes a Blu-ray Disc (BD) drive 5 and a host unit 11 . The structure of BD drive 5 and figure 1 The BD drive 5 shown is the same, but in this embodiment, instead of figure 1 The hybrid optical disc 10 a is shown, and the hybrid optical disc 10 a is inserted into the BD drive 5 .

[0047] Like the hybrid optical disc 10, the hybrid optical disc 10a includes a ROM layer L1 that can only read informa...

Abstract

In order to realize an information processing device capable of reducing the risk of the flow of recorded information, an optical disk device (1), which is an information processing device capable of recording and reproducing on a hybrid disk (10) provided with an RE layer (L2) on which information can be recorded additionally or rewritten, is provided with a destination restriction unit (61) which restricts the destination to save application data to only the RE layer (L2), the application data having been generated by executing an application program recorded on the hybrid disk (10). This enables to prevent the flow of the information caused by the saving of the application data on the HDD etc. of a PC.

Description

technical field [0001] The present invention relates to a technology for limiting storage addresses of data generated by applications. Background technique [0002] In recent years, the demand for small and lightweight personal computers (PC, Personal Computer) has increased, and small notebook PCs called "netbooks" released by various manufacturers have become popular among many users. The characteristics of these PCs are that the processing power of the CPU (Central Processing Unit, central processing unit) and the capacity of the storage medium are reduced to a minimum to achieve low cost, and the utilization of network resources is premised on the utilization of network resources in order to compensate for the above shortcomings. For example, network storage is used to save large data, or a service that operates in a browser is used instead of starting an application on a PC, so that the PC can be well utilized even if its performance is low. [0003] Based on the above...
