Recording medium, wobble cycle detection method, wobble information detection method, wobble information detection circuit, and information recording/reproduction device

摘要

The present invention is structured so that a track of a recording medium is divided into a carrier wave area that is continuously wobbled by a carrier wave wobble of a specific carrier wave cycle, and an address area that is wobbled by a special wobble that has a cycle different from the carrier wave wobble and a phase determined in response to data 0 and data 1 of information stored by a wobble.
