Abstract
Abstract Apparatus for transferring signals from a first magnetic tape to a second magnetic tape in different relative positions including a common capstan drive for both tapes with means controlled by the signals on the first tape for engaging the second tape with the capstan, a pickup head and a recording head associated respectively with the first tape and the second tape and means including a signal delay network coupling the two heads.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
Apparatus for transferring signals having predetermined relative positions on a first elongated signal bearing recording medium to a second signal receiving recording medium with different relative positions, said apparatus comprising a signal pickup head for generating electrical signals from said first medium, a signal recording head for recording signals on said second medium, a common drive means for driving said first medium past said signal pickup head and for driving said second medium past said recording head, said drive means comprising rotatable means, first control means for maintaining said first medium in contact with said rotatable means and thereby continuously driving said first medium and second control means for selectively engaging said second medium with said rotatable means and thereby selectively driving said second medium at recording speed, a coupling means including signal delay means electrically coupling said pickup head and said recording head, and actuating means coupled to said pickup head and responsive to signals at the output thereof for actuating said second control means whereby said second medium is moved past said recording head at recording speed substantially only when signals are present at the output of said pickup head.
Claim 2
Dependent Claim
192 words
Apparatus for transferring signals having predetermined relative positions on a first elongated signal bearing recording medium to a second signal receiving recording medium with different relative positions, said apparatus comprising a signal pickup head for generating electrical signals from said first medium, a signal recording head for recording signals on said second medium, a common drive means for driving said first medium past said signal pickup head and for driving said second medium past said recording head, said drive means comprising rotatable means, first control means for maintaining said first medium in contact with said rotatable means and thereby continuously driving said first medium and second control means for selectively engaging said second medium with said rotatable means and thereby selectively driving said second medium at recording speed, a coupling means including signal delay means electrically coupling said pickup head and said recording head, and actuating means coupled to said pickup head and responsive to signals at the output thereof for actuating said second control means whereby said second medium is moved past said recording head at recording speed substantially only when signals are present at the output of said pickup head.
Claim 3
Dependent Claim
56 words
Apparatus as set forth in claim 1 wherein said rotatable means is a rotatable drum, said first and second mediums being engageable with spaded surface portions thereof, said second control means comprises means for pressing said second medium against the surface of said drum, and said actuating means comprises a solenoid for actuating said pressing means.
Claim 4
Dependent Claim
58 words
Apparatus as set forth in claim 1 wherein said rotatable means comprises a pair of rotatable drums mounted with their axes of rotation in parallel, spaced relation and on opposite sides of said pickup and said recording heads, each of said mediums being engageable with the surfaces of both said drums by said first and second control means.
Claim 5
Dependent Claim
51 words
Apparatus as set forth in claim 1 wherein said rotatable means comprises a rotatable drum and each of said mediums extends around a major portion of the periphery thereof, said second medium being spaced from said periphery but being engageable with spaced portions of said periphery by said second control means.
Claim 6
Dependent Claim
65 words
Apparatus as set forth in claim 4 wherein said second control means comprises a pair of shoes disposed adjacent said spaced portions and movable theretoward to press said second medium against said periphery and a pair of links connected to said shoes, and said actuating means comprises a solenoid connected to said links for moving said shoes toward said periphery upon energization of said solenoid.
