Information replay methods and apparatus

Claim 3

A method as claimed in claim 1, including the steps of: varying said markings for designating different ones of said features for replay; instituting a further feature replay operation; sensing said varied markings; and controlling said further feature replay operation in response to said sensing of said varied markings to replay said different ones of said features.

Claim 4

A method as claimed in claim 1, wherein: each marking is selectively placed in a first position and in a second position to indicate, respectively, a desire to replay a particular feature and a desire to bypass replay of a particular feature; each marking is spaced from an adjacent marking in proportion to the length of a particular feature; said sensing of said marking proceeds from marking to marking in synchronism with an advance of said recording medium; and said recording medium is advanced at a playback speed in response to sensing of a marking in said first position, and selectively at a forward speed higher than said playback speed in response to sensing of a marking in said second position.

Claim 5

A method as claimed in claim 1, wherein: said support is a casing for said recording medium; and said markings are provided on said casing.

Claim 8

A method as claimed in claim 5, including the steps of: varying said first markings for designating different ones of said features for replay; instituting a further feature replay operation; sensing said varied first markings and said second markings; and controlling said further feature replay operation in response to said sensing of said varied first first markings and said second markings to replay said different ones of said features.

Claim 9

A method as claimed in claim 5, wherein: said sensing of said first and second markings includes a sensing of said first markings controlled by a sensing of said second markings.

Claim 10

A method as claimed in claim 5, wHerein: each first marking is selectively placed in a first position and in a second position to indicate, respectively, a desire to replay a particular feature and a desire to bypass replay of a particular feature; said sensing of said first and second markings includes a sensing of said first markings controlled by a sensing of said second markings; and said recording medium is advanced at a playback speed in response to sensing of a first marking in said first position, and selectively at a forward speed higher than said playback speed in response to a sensing of a first marking in said second position.

Claim 11

A method as claimed in claim 5, wherein: said support is a casing for said recording medium; and said first and second markings are provided on said casing.

Claim 12

In apparatus for selectively replaying a number of features recorded on a recording medium having a support, the improvement comprising in combination: a plurality of markings on said support indicative of the beginnings of said features and designating selected ones of said features for replay; means for instituting and effecting a feature replay operation; means for sensing said markings; and means connected to said replay instituting and effecting means and said sensing means for controlling said feature replay operation in response to said sensing of said markings to effect replay of said selected features.

Claim 13

In apparatus for selectively replaying a number of features recorded on a recording medium having a support, the improvement comprising in combination: a plurality of markings on said support indicative of the beginnings of said features and designating selected ones of said features for replay; means for instituting and effecting a feature replay operation; means for sensing said markings; and means connected to said replay instituting and effecting means and said sensing means for controlling said feature replay operation in response to said sensing of said markings to effect replay of said selected features.

Claim 14

Apparatus as claimed in claim 10, wherein: each marking is selectively adjustable to a first position and to a second position to indicate, respectively, a desire to replay a particular feature and a desire to bypass replay of a particular feature; each marking is spaced from an adjacent marking in proportion to the length of a particular feature; said sensing means include means proceeding from marking to marking in synchronism with an advance of said recording medium, for sensing the positions of said markings; and said control means include means connected between said sensing means and said replay instituting and effecting means for causing advance of said recording medium at a playback speed in response to a sensing of a marking in said first position, and selectively at a fast forward speed higher than said playback speed in response to sensing of a marking in said second position.

Claim 15

Apparatus as claimed in claim 10, wherein: said support is a casing for said recording medium; and said markings are provided on said casing.

Claim 16

In apparatus for selectively replaying a number of features recorded on a recording medium having a support, the improvement comprising in combination: a plurality of first markings on said support for designating selected ones of said features for replay; a plurality of second markings on said support indicative of the beginnings of said features; means for instituting and effecting a feature replay operation; means for sensing said first and second markings; and means connected to said replay instituting and effecting means and said sensing means for controlling said feature replay operation in response to said sensing of said first and second markings to effect replay of said selected features.

Claim 17

In apparatus for selectively replaying a number of features recorded on a recording medium having a support, the improvement comprising in combination: a plurality of first markings on said support for designating selected ones of said features for replay; a plurality of second markings on said support indicative of the beginnings of said features; means for instituting and effecting a feature replay operation; means for sensing said first and second markings; and means connected to said replay instituting and effecting means and said sensing means for controlling said feature replay operation in response to said sensing of said first and second markings to effect replay of said selected features.

Claim 18

Apparatus as claimed in claim 13, wherein: said sensing means include means for sensing said first markings, and means for sensing said second markings and for controlling said means for sensing said first markings in response to a sensing of said second markings.

Claim 19

Apparatus as claimed in claim 13, wherein: each first marking is selectively movable to a first position and to a second position to indicate, respectively, a desire to replay a particular feature and a desire to bypass replay of a particular feature; said sensing means include means for sensing the positions of said first markings, means for sensing said second markings and for controlling said means for sensing said first markings in response to a sensing of said second markIngs; and said means for controlling said feature replay operation include means for effecting advance of said recording medium at a playback speed in response to a sensing by said first sensing means of a first marking in said first position, and for effecting advance of said recording medium at a forward speed higher than said playback speed in response to a sensing by said first sensing means of a first marking in said second position.

Claim 20

Apparatus as claimed in claim 13, wherein: said support is a casing for said recording medium; and said first and second markings are provided on said casing.
