Abstract
Abstract An apparatus for recording an information signal in a track on the record carrier, such as, a helical scan video recorder, includes an input terminal (36) for receiving the information signal, a signal processor (10) for converting the information signal into a form in which it can be recorded on the record carrier (1) and a writing unit (30,32,34) for writing the converted information signal in the track on the record carrier. Further, the apparatus includes a unit for establishing the total length of the record carrier, viewed in time, a unit for establishing the actual position of the writing unit along the record carrier, viewed in time, and a unit (5,6) for transporting the record carrier. For recording an information signal of specific duration (T 2 ), on the record carrier (1), the record carrier is transported to a specific position along the record carrier for which holds that the remaining time for recording, at that specific position, substantially corresponds to the specific duration (T 2 ) of the information signal to be recorded.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
An apparatus for recording an information signal in a track on the record carrier, the apparatus comprising: input means for receiving the information signal; signal processing means for converting the information signal into a form for recording on the record carrier; writing means for writing the converted information signal in the track on the record carrier; means for establishing a total recording length of the record carrier, said total recording length being expressed in time; means for establishing an actual position of the writing means with respect to the record carrier, said actual position of the writing means being expressed in time; and means for positioning the writing means and the record carrier relative to each other, characterized in that the means for positioning positions the writing means and the record carrier relative to each other at a specific position on the record carrier, said specific position having a relationship with a remaining time for recording information on said record carrier, and that for recording an information signal of a specific duration on said record carrier, the means for positioning positions the writing means and the record carrier relative to each other at said specific position on the record carrier where the remaining time for recording at said specific position substantially corresponds to the specific duration of the information signal to be recorded.
Claim 2
Independent Claim
223 words
An apparatus for recording an information signal in a track on the record carrier, the apparatus comprising: input means for receiving the information signal; signal processing means for converting the information signal into a form for recording on the record carrier; writing means for writing the converted information signal in the track on the record carrier; means for establishing a total recording length of the record carrier, said total recording length being expressed in time; means for establishing an actual position of the writing means with respect to the record carrier, said actual position of the writing means being expressed in time; and means for positioning the writing means and the record carrier relative to each other, characterized in that the means for positioning positions the writing means and the record carrier relative to each other at a specific position on the record carrier, said specific position having a relationship with a remaining time for recording information on said record carrier, and that for recording an information signal of a specific duration on said record carrier, the means for positioning positions the writing means and the record carrier relative to each other at said specific position on the record carrier where the remaining time for recording at said specific position substantially corresponds to the specific duration of the information signal to be recorded.
Claim 3
Dependent Claim
120 words
Apparatus as claimed in claim 1, wherein the record carrier is a longitudinal record carrier, and the means for positioning comprises means for transporting the record carrier, characterized in that the means for transporting the record carrier transports the record carrier to a specific position along the record carrier, said specific position having a relationship with the remaining time for recording information on said record carrier, and that for recording an information signal of specific duration on said record carrier, the means for transporting transports the record carrier to said specific position along the record carrier such that the remaining time for recording at said specific position substantially corresponds to the specific duration of the information signal to be recorded.
Claim 4
Dependent Claim
100 words
Apparatus as claimed in claim 2, for recording a first information signal of a first predetermined duration, and a second information signal of a second predetermined duration on the record carrier, characterized in that the apparatus records the first information signal on the record carrier starting from the beginning of the record carrier, stops recording after said predetermined first duration, transports the record carrier to a specific location along the record carrier where the remaining time for recording at said specific position substantially corresponds to the second specific duration, and records the second information signal starting from said specific position.
Claim 5
Dependent Claim
64 words
Apparatus as claimed in claim 3, for recording a third information signal of a third predetermined duration on the record carrier, characterized in that the means for transporting transports the record carrier to the beginning of the record carrier, the apparatus further records the third information signal starting from the start position on the record carrier, and stops recording after said predetermined third duration.
Claim 6
Dependent Claim
70 words
Apparatus as claimed in claim 3, for recording a third information signal of a third predetermined duration on the record carrier, characterized in that the means for transporting transports the record carrier to a specific location along the record carrier where the remaining time for recording at said specific position substantially corresponds to the third specific duration, the apparatus further recording the third information signal starting from said specific position.
Claim 7
Dependent Claim
145 words
Apparatus as claimed in claim 3, characterized in that the apparatus further comprises: memory means for storing information relating to the duration of the first and second information signals recorded on the record carrier, and for storing information relating to the start positions of the recorded first and second information signals on said record carrier; means for storing information relating to a time duration of a third information signal to be recorded; and calculation means for calculating the time duration available for recording an information signal starting at the beginning of the record carrier until the location where the beginning of the second information signal has been recorded, for comparing the said time duration with the time duration of the third information signal, and for generating a first control signal when the time duration is smaller than the time duration of the third information signal.
Claim 8
Dependent Claim
80 words
Apparatus as claimed in claim 6, characterized in that the calculation means further calculates the remaining time for recording at a position along the record carrier substantially corresponding to the end position on the record carrier of the recording of the first information signal, compares said remaining time duration with the time duration of the third information signal, and generates a second control signal when said remaining time duration is smaller than the time duration of the third information signal.
Claim 9
Dependent Claim
59 words
Apparatus as claimed in claim 7, characterized in that, the apparatus records the third information signal in response to the absence of the second control signal, starting at a specific position along the record carrier where the remaining time for recording at said specific position substantially corresponds to the specific duration of the third information signal to be recorded.
Claim 10
