Abstract
Abstract An information recording medium comprises a plurality of information tracks (201) on which information is recorded, and separating regions (202) each for separating each of said information tracks from the other information tracks. Each of said separating regions includes a record section consisting of code means of a shape or magnitude different from code means in said information tracks.

Claim 1
Independent Claim
57 words
An information recording medium comprising a plurality of information tracks on which information is recorded, and separating regions each for separating each of said information tracks from the other information tracks, each of said separating regions including a record section consisting of code means of a shape or magnitude different from code means in said information tracks.
Claim 2
Dependent Claim
57 words
An information recording medium comprising a plurality of information tracks on which information is recorded, and separating regions each for separating each of said information tracks from the other information tracks, each of said separating regions including a record section consisting of code means of a shape or magnitude different from code means in said information tracks.
Claim 3
Dependent Claim
48 words
An information recording medium according to claim 1, wherein the record section of each of said separating regions has a length substantially perpendicular to the direction of information arrangement in the corresponding information track, said length being smaller than that of a record section of said information track.
Claim 4
Dependent Claim
33 words
An information recording medium according to claim 2, wherein the record section of each of said separating regions is located nearer one side of said information track in the direction of information arrangement.
Claim 5
Dependent Claim
29 words
An information recording medium according to claim 2, wherein the record sections of said separating regions include continuous and identical codes which will not appear in said information tracks.
Claim 6
Dependent Claim
43 words
An information recording medium according to claim 1, wherein the record section of each of said separating regions has a length perpendicular to the direction of information arrangement in the corresponding information track said length being variable along said direction of information arrangement.
Claim 7
Dependent Claim
92 words
An information recording medium comprising a plurality of information tracks on which information is recorded, and a plurality of common regions each for separating one of said information tracks from the adjacent information track in the direction of information arrangement and also for separating and discriminating said one information track from the adjacent information track in the direction substantially perpendicular to the direction of information arrangement, each of said common regions including a record section consisting of code means of a shape or magnitude different from code means in said information tracks.
Claim 8
Dependent Claim
92 words
An information recording medium comprising a plurality of information tracks on which information is recorded, and a plurality of common regions each for separating one of said information tracks from the adjacent information track in the direction of information arrangement and also for separating and discriminating said one information track from the adjacent information track in the direction substantially perpendicular to the direction of information arrangement, each of said common regions including a record section consisting of code means of a shape or magnitude different from code means in said information tracks.
Claim 9
Dependent Claim
47 words
