Abstract
Abstract An apparatus and method are provided for recording and/or reproducing signals relative to magnetic tapes provided in magazines of different configurations. Retaining means are provided for retaining and holding magazines of two different sizes and configurations, with respect to a common magnetic transducer for recording on and/or reproducing from the tapes of both magazines, depending upon which magazine is prepositioned on a support for the transducer. A common drive means may be provided for the tape of either magazine, thereby substantially simplifying the apparatus. In another form, auxiliary drive means is provided for the tape of one magazine, which auxiliary drive operates either separately from the drive for the tape of a magazine of a different shape or cooperates therewith. A removable or retractable retaining means for one of the magazines is provided, to permit the other magazine to be held in place without intervention thereby.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
301 words
An apparatus for transducing information with respect to magnetic tape contained within a plurality of magazines defined by respective substantially rectangular containers of different configurations including a first container the dimensions of which are smaller than those of a second container and wherein each container has openings along an edge wall thereof to permit access to the tape therein, comprising: a support including a housing, magnetic transducing means movably supported by said support, said support having an upwardly facing wall portion and first means supported by said wall portion for retaining when abutted thereagainst each magnetic tape magazine with its wall containing said openings positioned at an operative location on said housing, second retaining means movably supported by said support and means for moving said second retaining means from a retracted position whereby it is below the upper surface of said upwardly facing wall portion of said housing and out of the way of a magazine disposed on said upwardly facing wall portion to a position whereby a portion of said second retaining means protrudes beyond said upper surface and serves to engage and cooperate with said first retaining means in predeterminately locating and retaining said first magazine in its operative location on said upwardly facing wall portion during a transducing operation, third retaining means supported by said support for abutting and retaining a portion of the wall of the larger of said magazines so as to cooperate with said first retaining means in predeterminately locating said larger magazine on said support, and means for moving said transducing means from a first position wherein it is out of contact with the magnetic tape of a magazine disposed at said operative location to a second positioned wherein said transducing means engages said magnetic tape through an opening along said edge wall thereof.
Claim 2
Independent Claim
301 words
An apparatus for transducing information with respect to magnetic tape contained within a plurality of magazines defined by respective substantially rectangular containers of different configurations including a first container the dimensions of which are smaller than those of a second container and wherein each container has openings along an edge wall thereof to permit access to the tape therein, comprising: a support including a housing, magnetic transducing means movably supported by said support, said support having an upwardly facing wall portion and first means supported by said wall portion for retaining when abutted thereagainst each magnetic tape magazine with its wall containing said openings positioned at an operative location on said housing, second retaining means movably supported by said support and means for moving said second retaining means from a retracted position whereby it is below the upper surface of said upwardly facing wall portion of said housing and out of the way of a magazine disposed on said upwardly facing wall portion to a position whereby a portion of said second retaining means protrudes beyond said upper surface and serves to engage and cooperate with said first retaining means in predeterminately locating and retaining said first magazine in its operative location on said upwardly facing wall portion during a transducing operation, third retaining means supported by said support for abutting and retaining a portion of the wall of the larger of said magazines so as to cooperate with said first retaining means in predeterminately locating said larger magazine on said support, and means for moving said transducing means from a first position wherein it is out of contact with the magnetic tape of a magazine disposed at said operative location to a second positioned wherein said transducing means engages said magnetic tape through an opening along said edge wall thereof.
Claim 3
Dependent Claim
64 words
A magnetic transducing apparatus in accordance with claim 1 including a first electrically operated motor means located below said upwardly facing wall portion of said housing and operatively connected to said second means for advancing and retracting said second means to protrude a portion thereof beyond said upper surface of said upwardly facing wall portion and to draw said portion below said upper surface.
Claim 4
Dependent Claim
19 words
A magnetic transducing apparatus in accordance with claim 2 wherein said electrically operated motor means comprises a bistable solenoid.
Claim 5
Dependent Claim
138 words
A magnetic transducing apparatus in accordance with claim 2 wherein the smaller of said magazines contains supply and takeup reels for the magnetic tape thereof and first coupling means for said supply and takeup reels accessible to the outside of the housing of said smaller magazine, a second support operatively connected to said second means, second motor means supported by said second support and shaft means driven by said second motor means including second coupling means for connecting said shaft means to said first coupling means when said smaller of said magazines is operatively located on said upwardly facing wall of said housing, and an opening in said upwardly facing wall portion of said housing through which opening said second coupling means may pass and engage said first coupling means of a magazine operatively located on said support.
Claim 6
Dependent Claim
40 words
A magnetic transducing apparatus in accordance with claim 1 wherein said second and third means are respectively operable to engage portions of the edge walls of said magazines which are opposite those edge wall portions thereof containing said openings therein.
Claim 7
Dependent Claim
45 words
A magnetic transducing apparatus in accordance with claim 1 wherein said first means comprises a pair of L-shaped retainers which are located and operable to engage respective corner portions of each of said first and second containers when each is operatively located on said support.
Claim 8
Dependent Claim
48 words
A magnetic transducing apparatus in accordance with claim 1 wherein said second means comprises a pair of L-shaped retainers located to respectively engage respective opposite corners of the smaller of said magazines, which corners are located opposite said edge wall portion of said magazine containing said openings therein.
Claim 9
Dependent Claim
46 words
A magnetic transducing apparatus in accordance with claim 1 wherein said third means comprises a U-shaped retainer for the rear and side edge wall portions of the housing of the larger of said magazines which are opposite the edge wall portion thereof containing said openings therein.
