Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
The method of signal recording comprising, moving a recording medium along a predetermined path, rotating .[.a plurality of.]. .Iadd.at least three .Iaddend.circularly and axially spaced transducer heads, guiding the tape at an angle to the axis of rotation .Iadd.around said heads so as to be in contact therewith by an angle greater than the circumferential spacing between heads and less than 180° .Iaddend.and to such an angular extent that the heads scan sequentially in helical fashion along separate parallel longitudinal paths of equal width on the record medium, setting the rate of rotation such that a plurality of scans of equal length occur on the separate paths at predetermined spacing, and diverting the signal equally and in predetermined sequence to different ones of said heads.
Claim 2
Independent Claim
125 words
The method of signal recording comprising, moving a recording medium along a predetermined path, rotating .[.a plurality of.]. .Iadd.at least three .Iaddend.circularly and axially spaced transducer heads, guiding the tape at an angle to the axis of rotation .Iadd.around said heads so as to be in contact therewith by an angle greater than the circumferential spacing between heads and less than 180° .Iaddend.and to such an angular extent that the heads scan sequentially in helical fashion along separate parallel longitudinal paths of equal width on the record medium, setting the rate of rotation such that a plurality of scans of equal length occur on the separate paths at predetermined spacing, and diverting the signal equally and in predetermined sequence to different ones of said heads.
Claim 3
Dependent Claim
53 words
The method of signal recording defined in claim 1, comprising establishing a length of scan for each head slightly greater than the circular spacing of the heads whereby the scanning of said heads and diverting of the signal to different heads causes some redundant recording of information in different ones of said paths.
Claim 4
Dependent Claim
48 words
The method of claim 2, arranging the circular spacing of the heads such that each redundant recording includes information recorded in a path that is adjacent an edge of said medium has the corresponding redundant information recorded in an internal path that is bounded by other parallel paths.
Claim 5
Independent Claim
122 words
A method for recording on longitudinally moving recording tape, comprising transporting the tape lengthwise at a predetermined constant speed, providing a scanner having an axis of rotation and supporting at least three transducers at locations separated both .[.circularly.]. .Iadd.circumferentially .Iaddend.and axially around the scanning axis whereby the transducers follow separate parallel orbits about a common axis of rotation, and guiding the tape in a turn around the scanner at an angle to the axis of rotation and of such angular extent.Iadd., greater than the circumferential spacing between transducers and less than 180°, such .Iaddend.that each transducer follows a series of scans within a separate longitudinal path on the tape, the scans being of equal length and the paths being of equal width.
Claim 6
Independent Claim
122 words
A method for recording on longitudinally moving recording tape, comprising transporting the tape lengthwise at a predetermined constant speed, providing a scanner having an axis of rotation and supporting at least three transducers at locations separated both .[.circularly.]. .Iadd.circumferentially .Iaddend.and axially around the scanning axis whereby the transducers follow separate parallel orbits about a common axis of rotation, and guiding the tape in a turn around the scanner at an angle to the axis of rotation and of such angular extent.Iadd., greater than the circumferential spacing between transducers and less than 180°, such .Iaddend.that each transducer follows a series of scans within a separate longitudinal path on the tape, the scans being of equal length and the paths being of equal width.
Claim 7
Dependent Claim
19 words
A recording method as defined in claim 4, including distributing a signal to be recorded among the respective transducers.
