In operation 12, main frame will send drive system to by the compatibility information that the user generates.
In operation 13, the system controller of drive system is controlled the compatibility information in the compatibility information district that will be recorded on the dish.For example, system controller can be controlled the compatibility information in the recordable part that will be recorded in Lead-In Area.
Figure 11 is according to an embodiment of the invention according at the process flow diagram of the compatibility information that writes down on the information recording carrier with the method for data recording to the information recording carrier.With reference to Figure 11, in operation 21, dish is loaded onto in the drive system.
In operation 22, the system controller of drive system reads write protection label from the DDS of DMA on the dish.
In operation 23, system controller determines whether write protection label is set up.If write protection label is set up, because when write protection label is set up, write protection label prevents that data are recorded in the user data area of dish, and then this method proceeds to operation 28.
In operation 24, if write protection label also is not set up, then system controller compatibility information district of defining from the importing of dish or leading-out zone reads compatibility information and compatibility information is stored in the storer.
In operation 25, if drive system receives write order from main frame, then system controller is quoted the compatibility information of storage in storer 60.
In operation 26, based on compatibility information, system controller determines whether and can carry out write order to user data area.In other words, based on compatibility information, whether the system controller specified data can be recorded in the user data area.
In operation 27, based on compatibility information, if system controller determines and can carry out write order to user data area that then system controller is operated the user data area executive logging.In other words, be recordable if compatibility information is represented user data area, then system controller Control Driver system read and/or r/w cell with data recording in user data area.
Yet,, will represent that at operation 28 system controllers user data area is that the error message that can not write down sends main frame to if user data area can not write down.In other words, in operation 28, can not write down if compatibility information is represented user data area, then system controller 10 sends error message to main frame.
With reference to Figure 12 A to Figure 13, the write protection label of a kind of DDS based on dish, record compatibility information in the compatibility information district of dish and the writing of tray salver of dish forbids that the method whether hole information specified data can be recorded on the dish will be illustrated in greater detail.
Figure 12 A be illustrate about writing of tray salver forbid the hole information (below be called to write forbid hole information), be recorded in the diagrammatic sketch of the relation between the compatibility information of write protection label among the DDS of dish and dish.With reference to Figure 12 A, forbid hole information to writing, be recorded in write protection label among the DDS of dish and the compatibility information of dish is carried out the OR operation, and then whether be prevented from recording on the dish based on OR operating result specified data.
Be loaded onto to form to write in the tray salver of dish wherein in protection and forbid the hole.Forbid that the hole opens if write, thereby then dish is that write-protected data can not be recorded thereon.Forbid that the hole closes if write, then data can be recorded on the dish.In other words, write forbid that information specifies write-protect hole, hole is opened or close.The user can open or close to write and forbid the hole.Therefore, be written on the dish if the user wishes to prevent data, then he can open to write and forbid the hole.Then, when dish was loaded onto in the drive system, drive system can not be recorded in data on the dish.If the user wishes that dish is recordable, then he can close to write and forbid the hole.Then, when dish was loaded onto in the drive system, drive system can be with data recording to dish.
As mentioned above, the write protection label of the DDS of dish also the regulation dish whether by write-protect.
In one aspect of the invention, be write-protected if write at least one indicating panel of forbidding hole information, being recorded in the compatibility information of write protection label among the DDS of dish and dish, prevent that then data are recorded on the dish.Yet the write protection label of writing among the DDS that forbids the hole and be recorded in dish of tray salver is used to all prevent that data are recorded to whole dish.Therefore, forbid that hole information or write protection label indicating panel by write-protect, then do not consider compatibility information, prevent that data are recorded on whole the dish if write.Yet, based on corresponding compatibility information, forbid that hole information and write protection label all allow data to be recorded on the dish if write, determine whether data recording to each district of dish.
Therefore, do not consider compatibility information, whether the respective area that indicates on the dish is recordable, forbids that hole information or write protection label are set up as long as write, thereby whole dish can be by write-protect, and then data are prevented from recording in any one district of dish.Therefore, generate write protection label accidentally even work as the user, write and forbid that hole information and compatibility information contradict each other, data also can be prevented from recording on the dish.
Figure 12 B forbids hole information according to writing, is recorded in the write protection label among the DDS of dish and the compatibility information of dish, and whether display driver can be with the table of data recording to the dish.With reference to Figure 12 B, forbid that hole information has value " 0 " if write, then tray salver write forbid the hole be close and the dish also not by write-protect.If write protection label has value " 0 ", thereby then write protection label also is not set up data and still can be recorded on the dish.If the pre-determined bit of compatibility information has value " 0 ", then the fate on the dish is recordable.On the other hand, write the pre-determined bit of forbidding hole information, write protection label and compatibility information and can have value " 1 ", in the fate on data recording can also being gone up or coils to dish with expression.
With reference to Figure 12 B,, determine whether dish is recordable based on to writing the result who forbids hole information, write protection label and compatibility information execution OR operation.Therefore, only ought write and forbid all values of being set to " 0 " of hole information, write protection label and compatibility information, dish just is considered to recordable, thereby driver can be with data recording to dish.Otherwise dish is considered to write down.In other words, has only when writing and forbid all values of being set to " 0 " of hole information and write protection label, and compatibility information is when also to indicate the fate be recordable that data can be recorded to the fate of dish.Alternatively, forbid all values of being set to " 0 " of hole information and write protection label though write, unless compatibility information specifies the fate to write down, data can be recorded to the fate of dish.In addition, forbid hole information or write protection label value of being set to " 1 " if write, no matter compatibility information, data will be under an embargo and record on whole the dish.
