Optical recording medium, recording/reproducing apparatus and method, and recording medium storing program for executing the method

Abstract

An information recording medium includes an access control area in which access control data (ACD) is recorded, the ACD having common information set to allow a recording/reproducing apparatus that cannot recognize a predetermined function of the information recording medium to control access to the information recording medium; and an ACD state information area in which state information regarding one of defectiveness and recordability of an ACD block, at which the ACD is recorded in the access control area, is recorded.

1 . A recording/reproducing method comprising:
 writing access control data (ACD) to an access control area provided on an information recording medium, the ACD having common information for a corresponding predetermined function recognized by a compliant type of recording and/or reproducing apparatus and which is set to allow a non-compliant type of the recording/reproducing apparatus that cannot recognize a predetermined function of the information recording medium to control access to the information recording medium,   recording state information regarding one of defectiveness and recordability of an ACD block, at which the ACD is recorded in the access control area, in a temporary disc definition structure (TDDS) included in a temporary defect management area (TDMA) provided on the information recording medium.   
   
   
       2 . The recording/reproducing method of  claim 1 , wherein the ACD comprises at least one or more among an ACD_ID indicating an ID of the predetermined function, formatability information indicating and distinguishing between whether the information recording medium is formatable or is not formatable, TDMA recordability information indicating and distinguishing between whether the TDMA except for the TDDS is recordable or is not recordable, data area recordability/reproducibility information indicating and distinguishing between whether a data area provided on the information recording medium is recordable/reproducible or is not recordable/reproducible, or combinations thereof. 
   
   
       3 . The recording/reproducing method of  claim 2 , wherein, when the TDMA is assigned in the data area, the data area recordability/reproducibility information does not include recordability/reproducibility information indicating whether the TDMA assigned in the data area is recordable/reproducible. 
   
   
       4 . A recording/reproducing method comprising:
 reading access control data (ACD) from an access control area provided on an information recording medium, the ACD having common information for a corresponding predetermined function recognized by a compliant type of recording and/or reproducing apparatus and which is set to allow a non-compliant type of the recording/reproducing apparatus that cannot recognize a predetermined function of the information recording medium to control access to the information recording medium, reading state information regarding one of defectiveness and recordability of an ACD block, at which the ACD is recorded in the access control area, from a temporary disc definition structure (TDDS) included in a temporary defect management area (TDMA) provided on the information recording medium.   
   
   
       5 . The recording/reproducing method of  claim 4 , wherein the ACD comprises at least one or more among an ACD_ID indicating an ID of the predetermined function, formatability information indicating and distinguishing between whether the information recording medium is formatable or is not formatable, TDMA recordability information indicating and distinguishing between whether the TDMA except for the TDDS is recordable or is not recordable, data area recordability/reproducibility information indicating and distinguishing between whether a data area provided on the information recording medium is recordable/reproducible or is not recordable/reproducible, or combinations thereof. 
   
   
       6 . The recording/reproducing method of  claim 5 , wherein, when the TDMA is assigned in the data area, the data area recordability/reproducibility information does not include recordability/reproducibility information indicating whether the TDMA assigned in the data area is recordable/reproducible.
