<P>PROBLEM TO BE SOLVED: To provide a recording/reproducing device capable of improving inconvenience caused by the difference in distances in a radial direction from a rotary shaft to a pit in an optical disk having two or more recording layers, and an optical disk. <P>SOLUTION: An address storage zone 6d is disposed near the outer periphery of the read-in zone 6a of a lower recording layer 6, and in the address storage zone 6d, the address information of each area of a data zone 6b is recorded. The predetermined addresses of the virtual areas of areas A, B, and C are stored in the data zone 6b. Each area is disposed for each address number, the width in the radial direction of the area A arranged on the innermost side is largest among the three areas, and the width of the radial direction of the outermost area C is smallest among the three areas. <P>COPYRIGHT: (C)2004,JPO |
