Abstract

Abstract A recording and reproducing apparatus for recording and reproducing main information consisting of a plurality of programs longitudinally on and from a tape-shaped recording medium is arranged to have time information recorded along with the main information on the recording medium indicating a length of time from the beginning of each of the programs; and to control the travel of the recording medium on the basis of the time information reproduced from the recording medium.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 266 words
A reproducing apparatus for reproducing main information signals from a tape-shaped record bearing medium on which numeral information signals indicative of positions on said medium are recorded, the numeral value of said numeral information signals successively varying along the longitudinal direction of said tape-shaped record bearing medium, comprising: (a) moving means for moving said tape-shaped record bearing medium, in the longitudinal direction; (b) reproducing means for reproducing from said recording medium said main information signals and said numeral information signals; (c) manually operable means for instructing said apparatus to look up a desired position of said tape-shaped record bearing medium; (d) a first control means for setting the medium moving speed of said moving means to a first speed in response to look-up instruction given by said manually operable means; (e) a second control means for changing the medium moving speed of said moving means from said first speed to a second speed which is slower than said first speed in response to that a difference between a desired value corresponding to the desired position and the numeral value of said numeral information signals reproduced by said reproducing means becomes less than a predetermined value; and (f) a third control means for changing the medium moving speed of said moving means from said second speed to a third speed which is slower than said second speed in response to that a difference between the desired value and the numeral value of said reproduced numeral information signals becomes zero, said tape-shaped record bearing medium being moved at the third speed while said main information signals are recorded.
Claim 2
Dependent Claim 266 words
A reproducing apparatus for reproducing main information signals from a tape-shaped record bearing medium on which numeral information signals indicative of positions on said medium are recorded, the numeral value of said numeral information signals successively varying along the longitudinal direction of said tape-shaped record bearing medium, comprising: (a) moving means for moving said tape-shaped record bearing medium, in the longitudinal direction; (b) reproducing means for reproducing from said recording medium said main information signals and said numeral information signals; (c) manually operable means for instructing said apparatus to look up a desired position of said tape-shaped record bearing medium; (d) a first control means for setting the medium moving speed of said moving means to a first speed in response to look-up instruction given by said manually operable means; (e) a second control means for changing the medium moving speed of said moving means from said first speed to a second speed which is slower than said first speed in response to that a difference between a desired value corresponding to the desired position and the numeral value of said numeral information signals reproduced by said reproducing means becomes less than a predetermined value; and (f) a third control means for changing the medium moving speed of said moving means from said second speed to a third speed which is slower than said second speed in response to that a difference between the desired value and the numeral value of said reproduced numeral information signals becomes zero, said tape-shaped record bearing medium being moved at the third speed while said main information signals are recorded.
Claim 3
Dependent Claim 23 words
An apparatus according to claim 1, wherein said third control means is arranged to set said reproducing means reproducing said main information signals.
Claim 4
Dependent Claim 14 words
An apparatus according to claim 1, wherein the numeral informations indicate elapsed recording times.
Claim 5
Dependent Claim 26 words
An apparatus according to claim 3, wherein the numeral informations indicate a length of time from the beginning of each program of said main information signals.
Claim 6
Dependent Claim 29 words
An apparatus according to claim 4, wherein said desired position is a starting position of recording each program of said main information signals on said tape-shaped record bearing medium.
Claim 7
Dependent Claim 12 words
An apparatus according to claim 4, wherein the desired value is zero.
Claim 8
Dependent Claim 26 words
An apparatus according to claim 1, wherein said reproducing means includes a rotary head which is arranged to obliquely trace on said tape-shaped record bearing medium.
Claim 9
Dependent Claim 16 words
An apparatus according to claim 1, wherein said main information signal includes a digitized audio signal.
Claim 10
Dependent Claim 251 words
A reproducing apparatus for reproducing main information signals from a tape-shaped record bearing medium on which numeral information signals indicative of positions on said medium are recorded, the numeral value of said numeral information signals successively varying along the longitudinal direction of said tape-shaped record bearing medium, comprising: (a) moving means for moving said tape-shaped record bearing medium in the longitudinal direction; (b) reproducing means for reproducing from said recording medium said main information signals and said numeral information signals; (c) manually operable means for instructing said apparatus to look up a desired position of said tape-shaped record bearing medium; (d) a first control means for setting the medium moving speed of said moving means to a first speed in response to look-up instruction given by said manually operable means; (e) a second control means for changing the medium moving speed of said moving means from said first speed to a second speed which is slower than said first speed in response to that a difference between a desired value corresponding to the desired position and the numeral value of said numeral information signals reproduced by said reproducing means becomes less than a predetermined value; and (f) a third control means for setting said reproducing means reproducing said main information signals and for changing the medium moving speed to a third speed which is slower than said second speed, in response to that a difference between the desired value and the numeral value of said reproduced numeral information signals becomes zero.
Claim 11
Dependent Claim 251 words
A reproducing apparatus for reproducing main information signals from a tape-shaped record bearing medium on which numeral information signals indicative of positions on said medium are recorded, the numeral value of said numeral information signals successively varying along the longitudinal direction of said tape-shaped record bearing medium, comprising: (a) moving means for moving said tape-shaped record bearing medium in the longitudinal direction; (b) reproducing means for reproducing from said recording medium said main information signals and said numeral information signals; (c) manually operable means for instructing said apparatus to look up a desired position of said tape-shaped record bearing medium; (d) a first control means for setting the medium moving speed of said moving means to a first speed in response to look-up instruction given by said manually operable means; (e) a second control means for changing the medium moving speed of said moving means from said first speed to a second speed which is slower than said first speed in response to that a difference between a desired value corresponding to the desired position and the numeral value of said numeral information signals reproduced by said reproducing means becomes less than a predetermined value; and (f) a third control means for setting said reproducing means reproducing said main information signals and for changing the medium moving speed to a third speed which is slower than said second speed, in response to that a difference between the desired value and the numeral value of said reproduced numeral information signals becomes zero.
