Abstract
A recording medium, an address generating method, an address detection method and a recording and reproduction apparatus capable of extending the wobble address without any considerable wobble restructuring are disclosed. Virtual bits not recorded in the disc and expressed by the difference of the rule or the presence or absence of the information embedded in a part or the whole of the wobble address are generated. Thus, the extended address can be obtained without changing the number of bits of the address embedded in the wobble.
