Recording medium information may be copied and stored in a new information zone in a data area. Accordingly, if medium recognition of a lead-in area and/or a lead-out area fails, a recording medium may be recognized using the data recorded in the new information zone. ## Claims ### Claim 1 A recording medium comprising a lead-in area, a data area, and a lead-out area, wherein the data area comprises: a non-recording zone allocated adjacent to at least one of the lead-in area and the lead-out area; and an information zone allocated at an inner side of the non-recording zone and toward a center of the data area, the information zone for recording information about the recording medium. ### Claim 2 (depends on 1) The recording medium of claim 1, wherein the non-recording zone is allocated adjacent to each of the lead-in area and the lead-out area. ### Claim 3 (depends on 2) The recording medium of claim 2, wherein the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-in area. ### Claim 4 (depends on 2) The recording medium of claim 2, wherein the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-out area. ### Claim 5 (depends on 1) The recording medium of claim 1, wherein the information about the recording medium is recorded in at least one of the lead-in area and the lead-out area and is also copied and stored in the information zone. ### Claim 6 (depends on 1) The recording medium of claim 1, wherein the non-recording zone covers about 30% of the recording medium from its inner and/or outer circumference. ### Claim 7 (depends on 6) The recording medium of claim 6, wherein the information zone is not allocated in the 30% of the recording medium from its inner and/or outer circumference. ### Claim 8 A recording/reproducing apparatus comprising: an optical pickup configured to irradiate light onto a recording medium to record data thereon; a memory configured to store information about ranges of a valid data area and a new information zone of a recording medium, which are obtained in advance by performing a test; and a control unit configured to allocate a non-recording zone adjacent to at least one of a lead-in area and a lead-out area in a data area of a target recording medium, to allocate an information zone at an inner side of the non-recording zone toward a center of the data area, based on the information stored in the memory, and to control recording medium information to be recorded in the information zone. ### Claim 9 (depends on 8) The recording/reproducing apparatus of claim 8, wherein the non-recording zone is allocated adjacent to each of the lead-in area and the lead-out area. ### Claim 10 (depends on 9) The recording/reproducing apparatus of claim 9, the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-in area. ### Claim 11 (depends on 9) The recording/reproducing apparatus of claim 9, wherein the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-out area. ### Claim 12 (depends on 8) The recording/reproducing apparatus of claim 8, wherein the information about the recording medium is recorded in at least one of the lead-in area and the lead-out area and is copied to and stored in the information zone. ### Claim 13 (depends on 8) The recording/reproducing apparatus of claim 8, wherein the non-recording zone covers about 30% of the target recording medium from its inner and/or outer circumference. ### Claim 14 A recording method comprising: allocating a non-recording zone adjacent to at least one of a lead-in area and a lead-out area in a data area of a target recording medium; allocating an information zone at an inner side of the non-recording zone toward a center of the data area, based on ranges of a valid data area which are obtained in advance by performing a test and which is stored in a memory of the recording/reproducing apparatus; and recording information about the recording medium in the information zone. ### Claim 15 (depends on 14) The recording method of claim 14, wherein the non-recording zone is allocated adjacent to each of the lead-in area and the lead-out area. ### Claim 16 (depends on 15) The recording method of claim 15, wherein the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-in area. ### Claim 17 (depends on 15) The recording method of claim 15, wherein the information zone is allocated at an inner side of the non-recording zone adjacent to the lead-out area. ### Claim 18 (depends on 14) The recording method of claim 14, wherein the information about the recording medium is recorded in at least one of the lead-in area and the lead-out area and is copied and stored in the information zone. ### Claim 19 (depends on 14) The recording method of claim 14, wherein the non-recording zone covers about 30% of the target recording medium from its inner and/or outer circumference. ### Claim 20 (depends on 19) The recording method of claim 19, wherein the information zone is not allocated in the 30% of the target recording medium from its inner and/or outer circumference.
