Abstract
Abstract Monochrome and color television recording and playback circuitry for coupling of a video magnetic transducer head with a standard broadcast television receiver. The transducer head preferably includes a plurality of head units for recording respective color television signals with provision for selectively recording a monochrome signal on successive channels with the use of one only of the head units.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
157 words
A color television recording system comprising receiver circuitry for supplying respective color television signals, a video transducer head for coupling to a record medium to record the respective color television signals on the record medium, and coupling means connected to said receiver circuitry and to said transducer head for transmitting the respective color television signals to said transducer head during recording. said transducer head comprising at least two video head units scanning respective first and second channels of a record medium for recording respective color television signals containing information relative to a color image on said channels during a color image recording operation, means for selectively rendering one of said head units inoperative during a monochrome signal recording operation and for supplying a monochrome signal containing luminance information to the other of said head units, and means for selectively recording a monochrome signal on each of said first and second channels during the monochrome signal recording operation.
Claim 2
Dependent Claim
157 words
A color television recording system comprising receiver circuitry for supplying respective color television signals, a video transducer head for coupling to a record medium to record the respective color television signals on the record medium, and coupling means connected to said receiver circuitry and to said transducer head for transmitting the respective color television signals to said transducer head during recording. said transducer head comprising at least two video head units scanning respective first and second channels of a record medium for recording respective color television signals containing information relative to a color image on said channels during a color image recording operation, means for selectively rendering one of said head units inoperative during a monochrome signal recording operation and for supplying a monochrome signal containing luminance information to the other of said head units, and means for selectively recording a monochrome signal on each of said first and second channels during the monochrome signal recording operation.
Claim 3
Dependent Claim
29 words
The system of claim 1 with means for shifting said other of said head units to register selectively with said first and second channels during said monochrome recording operation.
Claim 4
Dependent Claim
29 words
The system of claim 1 with means for recording audio signals related to said monochrome signal selectively in said first and second channels during said monochrome signal recording operation.
