When being inserted into CD in the equipment, execution dish identification step 40 (DSC_REC) at first.This step is well known in the art, and can relate to the parameter (for example focusing on) of the radiation of at first determining to be reflected so that determine whether CD is CD, DVD or BD type in first substep.After the type of identification placing, obtain other fundamental base information, so that determine the position of basic read/write parameters and Lead-In Area, block and leading-out zone.Should be pointed out that in information that fundamental base information can be from be encoded in swing or the information from be recorded in Lead-In Area and obtain.
In step 41, whether the identification of inspection dish is successful.As the fruit tray recognition failures, can use without any the essential information of relevant described dish, in step 42, described dish is refused as the dish that damages so.
Be identified as merit as fruit tray, so then carry out installation steps 43 (MOUNT), wherein the management information of reading and recording in Lead-In Area in first substep.This information generally includes the information that allows the access logic layer.For example, in the CD-RW system, this is corresponding to reading catalogue listing (TOC), and in the DVD-RW system, it is corresponding to reading format dish controll block (FDCB), and in the BD-RE system, it is corresponding to reading (temporarily) defect management (T) DMA.The information of Cun Zaiing is the form of user data on the display disc there, for example UDF or ISO 9660, and the position at indication file information table place.In next substep, access file information table and finish the installation of dish.
In step 44, whether the installation of inspection dish is successful.As the successful installation of fruit tray, so in step 45 terminal user can be for example by reading and/or record data use described dish.
Because following type of error, the installation of dish may be unsuccessful fully:
-when reading basic disc management information, running into mistake, the result does not obtain the information of the Format Type that relevant user data has, the perhaps information of the position at relevant disc recording file allocation information place on described dish in installation steps;
-the mistake that when reading file allocation information, runs into.
When in known optical drive, running into mistake, described dish is refused as the dish that damages.Yet, in according to method and apparatus of the present invention, be identified as merit but the installation failure of dish as fruit tray, what replace so described dish is refused as the dish that damages is to allow the dish of reformatting rewritable type in formatting step 46 (FORMAT).This is based on following understanding: having only the fundamental base identification information that can extract from described swing is necessary for the format dish.Should be pointed out that when running into the type of error of back, as later on will as described in, can the format before carry out recovering step (RECOV).
The process of formatting optical disc is known, and common some options are available.The process that is called rule schemataization in this area is the conventional physical format mode that is used for the CD such as CD or DVD.After the rule schemata process, described dish is formatd on Physical layer fully.Described formatting procedure comprises record Lead-In Area (LI), write block (DZ), write leading-out zone (LO) and if use defect management, then comprise checking data block and initialization defect management alternatively.Should be pointed out that can be for example by the management of operation system of computer operational deficiencies outside described equipment.Second type formatting procedure is called backstage format in the art, and it is the formatting procedure that uses in register during the described dish at running background.After the backstage formatting procedure was finished, described dish was physically formatd on Physical layer fully.User data can record on the described dish during the formatting procedure of backstage.The backstage formatting procedure can may further comprise the steps:
-initialization defect management;
-the data block is carried out deicing (de-ice), this type according to CD can be chosen wantonly;
-finish to import and the derivation block;
-previous the ejection finished (if applicable);
-on the previous dish that ejects, restart the backstage to format;
-verification (selecting by host computer alternatively).
Usually, for the user, the backstage is formatd the time that is regarded as and is gone up much effective solution, because during the initial phase of backstage formatting procedure, have only the data of minimum number to be recorded on the described dish, described thereafter dish can be used by application/user.The dish that backstage formatting procedure activates on it can also be during using the moment of not visiting described dish on the backstage by described device formatization.
In view of when the previous effort that described dish is installed is failed, expecting that this dish has this fact of zone that can not use probably, in a preferred embodiment of the invention, service regeulations format rather than backstage format.This allows the checking procedure 48 (VERIF) of complete before using described dish.Verification is the process that reads and check all message block in the block of described dish.If find that message block is unreliable, should adopt defect management to avoid this message block is used for recording user information so.
About defect management, different possibility may be available, for example with normal user data size and normal defects replace the corresponding rule dish form in zone, with less user data size and bigger defective replace the corresponding severe use dish form in zone and with the big or small and minimum regional corresponding slight use dish form of defective replacement of the user data of maximum.In a preferred embodiment of the invention, in view of this dish when the previous effort that described dish is installed is failed has this fact of zone that can not use probably, use severe use dish form.
