Abstract
Abstract An information storage carrier for storing intelligence Information along a path on the medium extending from an upstream location to a downstream location. The carrier is comprised of an information storage member having a surface upon which the information is stored. A first series of lineal regions are arranged on the surface, each region of such first series of regions containing information representative of a portion of the total information stored in the first series regions. A second series of lineal regions is arranged on the surface, spaced from the first series of lineal regions, each region of the second series of regions containing information representative of same portion of the information stored in a corresponding region of the first series of lineal regions, thereby providing duplication of the information at two locations on the storage member. Additional series of lineal regions can be arranged on the surface, thereby providing additional duplicated information locations on the storage member, the additional number of series of lineal regions depending upon the length of the program contained in each series and the total available time on the storage medium.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
An information storage carrier for storing intelligence information along a path on said carrier, said carrier comprising: an information storage member having a surface upon which said information is stored; a first series of lineal regions arranged on said surface and defining a program of information, each region of said first series of regions containing information representative of a portion of said program information; and a second series of lineal regions arranged on said surface and spaced from said first series of lineal regions, each region of said second series of regions containing information representative of the same respective portion of the information stored in a corresponding region of said first series of lineal regions, thereby providing duplication of said program information at two locations on said storage member.
Claim 2
Dependent Claim
129 words
An information storage carrier for storing intelligence information along a path on said carrier, said carrier comprising: an information storage member having a surface upon which said information is stored; a first series of lineal regions arranged on said surface and defining a program of information, each region of said first series of regions containing information representative of a portion of said program information; and a second series of lineal regions arranged on said surface and spaced from said first series of lineal regions, each region of said second series of regions containing information representative of the same respective portion of the information stored in a corresponding region of said first series of lineal regions, thereby providing duplication of said program information at two locations on said storage member.
Claim 3
Dependent Claim
83 words
The information storage carrier as claimed in Claim 1, comprising: N additional series of lineal regions arranged on said surface, each of said N series of lineal regions spaced from adjacent series of lineal regions, each region of each of said N series of regions containing information representative of the same respective portion of the information stored in corresponding regions of said first and second series of lineal regions, thereby providing duplication of said program information at N locations on said storage member.
Claim 4
Dependent Claim
103 words
The information storage carrier as claimed in Claim 1, wherein: the regions of said first series of lineal'regions are arranged continuously and contiguously along said path from a program-start upstream location to a program-end downstream location, thereby defining a first program information band on said storage member between said start and said end locations; and the regions of said second series of lineal regions are arranged continuously and contiguously along said path to define a second program information band on said storage member between corresponding program-start and program-end locations, said second program information band being spaced downstream from said first program information band.
Claim 5
Dependent Claim
46 words
The information storage carrier as claimed in Claim 1, wherein: the regions of said first series of lineal regions are arranged interleaved with the regions of said second series of lineal regions along said path to define alternate first and second regions spaced along said path.
Claim 6
Dependent Claim
70 words
The information storage carrier as claimed in Claim 3, wherein: said storage member is disc-shaped; said path comprises a plurality of concentric substantially circular segments; said first information band extends from a first radial distance to a second radial distance from the center of said storage medium; and said second information band extends from a third -radial distance to a fourth radial distance from the center of said storage medium.
Claim 7
Dependent Claim
46 words
6 . The information storage carrier as claimed in Claim 5, wherein: said first radial distance is less than said second radial distance; said second radial distance is less than said third radial distance; and said third radial distance is less than said fourth radial distance.
Claim 8
Dependent Claim
35 words
The information storage carrier as claimed in Claim 4, wherein: said storage member is disc-shaped; and said regions of said first and second series of lineal regions are arranged in alternating concentric, substantially circular segments.
Claim 9
Dependent Claim
51 words
The information storage carrier as claimed in Claim 1, wherein: said storage member is disc-shaped; and each region said first and second series of lineal regions is substantially circular in shape and contains all the video and associated audio information necessary to represent a complete picture frame of a television signal.
Claim 10
Dependent Claim
89 words
The information storage carrier as claimed in Claim 2, wherein: said storage member is disc-shaped; N is greater than two; and said regions of said first, second, and N series of lineal regions are arranged with the first region of each series cascaded in the order of first through Nth in radially progressing concentric circular segments, followed by the next region in order from each series cascaded in the order of first through Nth, the last region of each series also cascaded in the order of first through Nth.
Claim 11
Dependent Claim
78 words
The information storage carrier as claimed in Claim 2, wherein: said storage member is disc-shaped; N is greater than two; the regions of said first series of lineal regions are arranged continuously and contiguously along said path, thereby defining a first program information band on said storage member; and the regions of said second through Nth series of lineal regions are similarly arranged continuously and contiguously along said path, thereby defining, respectively, second through Nth program information bands.
