Optical recording medium having pit rows on every other boundary and reproducing method thereof

A reproducing method for an optical recording medium, the optical recording medium comprising, (1) grooves and lands which are alternately arranged and (2) pit rows which are formed on every other boundary by digging boundaries between said adjoining grooves and land so that address information of a recording/reproducing track is recorded, said method comprising:

• the first step of when said grooves or lands as the recording/reproducing track in said optical recording medium is scanned by a light in a direction of the track, reading out an address of the recording/reproducing track from said pit rows;
• the second step of discriminating whether the recording/reproducing track which is scanned by the light is said groove or land;
• and
• wherein said address of the recording/reproducing track are recorded by said pit rows so that its value increases or decreases by two at a time,
• either of said grooves or lands where said pit rows have been formed on said boundary sections between said grooves and lands are managed by an address which is same as of said recording/reproducing track, the other address of either of said grooves or lands is specified by adding and subtracting one to or from the address of the recording/reproducing track.

• (address by pit rows)+(a total number of tracks)/2 so as to be specified.
