optical disk for recording / playback with zigzag flexible kopffeldern and recording / player for use in the same

摘要

A recording/reproducing optical disk of the present invention comprises a first recording section formed on a spiral track in an area in the shape of a land, a second recording section formed on the spiral track in an area in the shape of a groove, the second recording section being adjacent to the first recording section, a first half header section in which first address information of the first recording section is recorded, and a second half header section, in which second address information of the second recording section is recorded, and which is disposed in pair with the first half header section in a zig-zag shifted manner, wherein the first half header section (e.g. HF1) and the second half header section (e.g. HF4) are located ahead of the first recording section (e.g. RF2) to assume a first positional relation relatively to the first recording section and the first half header section (e.g. HF1) and the second half header section (e.g. HF2) are located ahead of the second recording section (e.g. RF5) to assume a second positional relation other than the first positional relation relatively to the second recording section.
