Embodiment Construction

[0032] Embodiments of the present invention will be described below with reference to the drawings.

[0033] figure 1 is a correlation diagram of addresses of the multi-layer optical disc in the first embodiment of the present invention. 101 represents the physical sector number of the sector, that is, Physical Sector Number (hereinafter referred to as PSN), 102 represents the address of the data embedded in the cluster unit, namely Address Unit Number (hereinafter referred to as AUN), and 103 represents the physical ADIP address of the swing, namely The actual address of the Physical ADIP Address (hereinafter referred to as PAA), 104 indicates the address actually embedded in the wobble of the Physical ADIP Address (hereinafter referred to as PAAW), 105 indicates the scrambling circuit, and 106 indicates exclusive OR (Ex-OR). Here, scrambling refers to a process aimed at converting the value of each bit of an address and converting regularly in one operation process. An ex...

Abstract

Obtain an expanded address without altering the bit number of an address which is embedded in a Wobble. Generate a virtual bit which is not recorded in a disc, and which is expressed by the disparity from the rules and the presence or absence of information embedded in part or all of the wobble address.

Description

technical field [0001] The present invention relates to a recording medium on which an address is recorded, such as an optical disc, a method for reproducing and recording the optical disc, a reproducing device and a recording device for recording and reproducing data from the recording medium. Background technique [0002] of Patent Document 1 Figure 6 Indicates the relationship between the address information of Blu-ray Disc (Blu-ray Disc), paragraph [0010] records "address unit number (AUN) such as Figure 6 As shown, it is associated with the physical sector number, and is associated with the physical ADIP (Address In Pre-groove: address pre-groove) address, so it is usefully used as reference information for finding the recording position". According to the attached drawing, in the In the relationship between the physical sector number (Physical Sector Number, PSN) assigned to the data of the sector unit and the physical ADIP address (Physical ADIP Address, PAA) embedde...
