Pyatt - Web page: https://patentgrep.com/patent/US5351159A ## CPC - G11B 23/046: {Indicating means, e.g. quantity of tape} - G11B 23/08714: {Auxiliary features (sensing such features G11B15/06)} - G11B 23/107: using one reel or core, one end of the record carrier coming out of the magazine or cassette - G11B: INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER (recording measured values in a way that does not require playback through a transducer G01D9/00; recording or playback apparatus using mechanically marked tape, e.g. punched paper tape, or using unit records, e.g. punched or magnetically marked cards G06K; transferring data from one type of record carrier to another G06K1/18; circuits for coupling output of reproducer to radio receiver H04B1/20; gramophone pick-ups or like acoustic electromechanical transducers or circuits therefor H04R) ## Abstract This magnetic tape cartridge has the same exterior dimensions as a conventional 3480-type magnetic tape cartridge but houses different media. To clearly identify the media contained in the cartridge, a label receiving recess in included on the back of the cartridge. A human readable and machine readable label can be inserted into this recess to identify the media contained in this cartridge. Additional label recesses are provided juxtaposed to the media identification recess and on the top and side of the cartridge to receive user installed labels to uniquely identify the cartridge. ## Claims ### Claim 1 A magnetic tape cartridge comprising: an exterior housing having a top side, a bottom side, a back side and a front side thereto for enclosing a single reel of magnetic tape; first recess means of predetermined dimensions located on said back side of said exterior housing for receiving a label identifying data storage characteristics of said magnetic tape; second recess means of predetermined dimensions, located on said back side of said exterior housing juxtaposed to said first recess means, for receiving a label identifying said magnetic tape cartridge; and means, mechanically imprinted into said front side of said exterior housing for defining data storage characteristics of said magnetic tape. ### Claim 2 (depends on 1) The magnetic tape cartridge of claim 1 wherein said exterior housing has the exterior dimensions of a 3480-type magnetic tape cartridge. ### Claim 3 (depends on 1) The magnetic tape cartridge of claim 1 wherein said first recess means is substantially rectangular in shape. ### Claim 4 (depends on 1) The magnetic tape cartridge of claim 1 wherein said first recess means is formed of different depth into said back side of said exterior housing than said second recess means. ### Claim 5 (depends on 1) The magnetic tape cartridge of claim 1 wherein said second recess means is substantially rectangular in shape. ### Claim 6 (depends on 1) The magnetic tape cartridge of claim 1 wherein said first recess means is formed to be different in height from said top side of said exterior housing to said bottom side of said exterior housing than said second recess means. ### Claim 7 (depends on 1) The magnetic tape cartridge of claim 1 further comprising: third recess means of predetermined dimensions located on said top side of said exterior housing for receiving a label identifying data storage characteristics of said magnetic tape. ### Claim 8 (depends on 7) The magnetic tape cartridge of claim 7 further comprising: fourth recess means of predetermined dimensions located on said top side of said exterior housing for receiving a label identifying said magnetic tape cartridge. ### Claim 9 (depends on 1) The magnetic tape cartridge of claim 1 wherein said defining means comprises: a plurality of coding apertures located on said front side of said exterior housing. ### Claim 10 (depends on 1) The magnetic tape cartridge of claim 1, wherein said exterior housing has a right side and a left side, further comprising: side recess means of predetermined dimensions, located on at least one of said right side and said left side, for receiving a label identifying said magnetic tape cartridge. ### Claim 11 A magnetic tape cartridge containing a single reel of magnetic tape, said magnetic tape cartridge being received into a tape drive unit for reading/writing data on said magnetic tape, comprising: housing means, being substantially rectangular in shape and having a front side, a back side, a top side and a bottom side thereto; first recess means of predetermined dimensions located on said back side of said housing means; second recess means of predetermined dimensions located on said back side of said housing means and juxtaposed to said first recess means for receiving a label identifying said magnetic tape cartridge; label means, inserted into said first recess means, for identifying data storage characteristics of said magnetic tape; and means, mechanically imprinted into said front side of said exterior housing for defining data storage characteristics of said magnetic tape. ### Claim 12 (depends on 11) The magnetic tape cartridge of claim 11 wherein said first recess means is substantially rectangular in shape. ### Claim 13 (depends on 11) The magnetic tape cartridge of claim 11 wherein said first recess means is formed of different depth into said back side of said housing means than said second recess means. ### Claim 14 (depends on 11) The magnetic tape cartridge of claim 11 wherein said second recess means is substantially rectangular in shape. ### Claim 15 (depends on 11) The magnetic tape cartridge of claim 11 wherein said first recess means is formed to be different in height from said top side of said housing means to said bottom side of said housing means than said second recess means. ### Claim 16 (depends on 11) The magnetic tape cartridge of claim 11 further comprising: third recess means of predetermined dimensions located on said top side of said housing means for receiving a label identifying data storage characteristics of said magnetic tape. ### Claim 17 (depends on 16) The magnetic tape cartridge of claim 16 further comprising: fourth recess means of predetermined dimensions located on said top side of said housing means for receiving a label identifying said magnetic tape cartridge. ### Claim 18 (depends on 11) The magnetic tape cartridge of claim 11 wherein said defining means comprises: a plurality of coding apertures located on said front side of said housing means. ### Claim 19 (depends on 11) The magnetic tape cartridge of claim 11, wherein said housing means has a right side and a left side, further comprising: side recess means of predetermined dimensions, located on at least one of said right side and said left side, for receiving a label identifying said magnetic tape cartridge.
