Patent ID: 7864636

Claim:
An optical recording medium for use with a recording and/or reproducing apparatus, the optical recording medium comprising: a plurality of recording layers, a first sector address being assigned to a first recording layer which is a complement of a second sector address assigned to a second recording layer adjacent to the first recording layer, a sector address of each of the remaining recording layers being assigned such that a difference between the assigned sector address of each of the remaining recording layers and a sector address of a recording layer which is two layers below the recording layer of the assigned sector address is the same as a predetermined offset value, the first recording layer being any one of the bottom recording layer and the top recording layer from among the plurality of recording layers, wherein, if the number of recording layers is an even number, the offset value is less than or equal to a value obtained by dividing a spare address space, which remains after storing data, by (the number of the recording layers)/2, and wherein, if the number of the recording layers is an odd number, the offset value is less than or equal to a value obtained by dividing a spare address space, which remains after storing data, by (the number of the recording layers +1)/2.
