As previously mentioned, increasing publication being arranged at present is to sell by hardware memory devices such as memory card or the like.At this moment, except that the data content of being sold, hardware memory devices itself often also has unnecessary storage volume, uses for the user.Please refer to the synoptic diagram of Fig. 1 and Fig. 2,, the region of data storage in the hardware memory devices can be divided into rewritable district 1 and write-protected zone 2 according to the present invention.(it should be noted that icon only is signal; In fact rewritable district 1 or write-protected zone 2 do not need to fuse separately, and can be the block of dispersion.) within the rewritable district 1, the tolerable user writes and deleted data, promptly aforementioned it " unnecessary storage volume ".Data in the write-protected zone 2 do not allow that then the user writes and deletes, and can store the publication of desiring to sell in it, for example the MP3 music.With the mode that region of data storage is distinguished, for example (but being not limited to) can declare into write-protect with the part of region of data storage by the declaration instruction.
In the write-protected zone 2, can divide into hidden area 21 and non-hidden area 22 again.As its name suggests, the data in the hidden area 21 are hidden for the user, that is the user can't directly read data in the hidden area 21 via general fashion; 22 of non-hidden areas appear, that is the user does not need by specific step, only need normal executive routine, can directly read the data in the hidden area 21.
According to one of them embodiment of the present invention; can the data of literary property will be had; or other desire protection is in case the data of duplicating; be stored in the hidden area 21; and can read the application program (executive routine of data for example of these data; as MP3 music program, multimedia video playing program or the like), be stored in the non-hidden area 22.
Except the differentiation of above-mentioned storage area, the present invention still has following characteristics.Hidden area 21 in the hardware memory devices, declaration become that playing device can be handled but the direct data layout that reads of identification.For example, suppose that playing device is a personal computer, then the data layout of hidden area 21 can be declared as CDFS (Compact Disk File System).Personal computer can be handled the data of CDFS data layout, but, when reading hidden area 21, can not this data field of identification be real CD-ROM but by the mode of instruction declaration, because this data field in fact is disk but not CD, the mode difference of its actual data ordering and management.Therefore, be CD-ROM, but personal computer can not read the data in the hidden area 21 according to the CD-ROM data layout known to it even show this district on the screen.
According to the present invention, personal computer must be by loading the application program in the non-hidden area 22, could read data in the hidden area 21 according to this application program, and in data read process, can't copy data.
In detail, in the general data play operation, when personal computer desires to come reading of data according to the application program in the Storage Media, from Storage Media, application program is moved the program code storage district (code segment) that is stored in storer, and the data of correspondence are stored in the lump the region of data storage (data segment) of storer.Because data take out of from Storage Media, be downloaded in the storer of personal computer, so certain, the person who is ambitious or tenacious of purpose can be with these data from the storer bootlegging to other place.
