Abstract
Abstract This disclosure pertains to a cartridge containing an endless magnetic tape having recorded information in combination with a second spool of endless tape having written information thereon. The two spools are linked together so that both tapes are synchronously driven by a conventional tape player adapted to operate the magnetic spool alone. The user views the information on the indicating tape while listening to the playback of the recorded signal by utilizing a magnifying lense adapted to selectively enlarge each longitudinal track of written information, such as lyrics, corresponding to the longitudinal tracks of related signal, such as music.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
An indicating apparatus comprising a housing adapted to contain an endless magnetically susceptible strip born by a first reel and a first idler, an endless indicia bearing strip born by a second reel and a second idler, driving means to drive said magnetically susceptible strip and said indicia bearing strip at a synchronous rate, said magnetically susceptible strip and said indicia bearing strip adapted to have substantially identical peripheral lengths, viewing means adapted to permit viewing of said indicia bearing strip through a first opening in said housing, transport means to transport said magnetically susceptible strip utilizing a second opening in said housing, coupling means adapted to permit magnetic coupling to said magnetically susceptible strip.
Claim 2
Dependent Claim
115 words
An indicating apparatus comprising a housing adapted to contain an endless magnetically susceptible strip born by a first reel and a first idler, an endless indicia bearing strip born by a second reel and a second idler, driving means to drive said magnetically susceptible strip and said indicia bearing strip at a synchronous rate, said magnetically susceptible strip and said indicia bearing strip adapted to have substantially identical peripheral lengths, viewing means adapted to permit viewing of said indicia bearing strip through a first opening in said housing, transport means to transport said magnetically susceptible strip utilizing a second opening in said housing, coupling means adapted to permit magnetic coupling to said magnetically susceptible strip.
Claim 3
Dependent Claim
56 words
The indicating apparatus as claimed in claim 1 wherein said magnetically susceptible strip is magnetically encoded in a number more than one of parallel longitudinal tracks extending parallel to the edges of said magnetically susceptible strip, said indicia bearing strip adapted to have indicia contained within tracks equal in number to said number more than one.
Claim 4
Dependent Claim
27 words
The indicating apparatus as claimed in claim 1 wherein said indicia bearing strip contains indicia visually related to the intelligence magnetically encoded upon said magnetically susceptible strip.
Claim 5
Dependent Claim
34 words
The indicating apparatus as claimed in claim 1 further comprising a magnifying lense adapted to engage said housing, means to magnify the outermost surface of said indicia bearing strip appearing through said first opening.
Claim 6
Dependent Claim
35 words
The indicating apparatus as claimed in claim 4 further comprising means to adjust the focal axis of said magnifying lense to intersect said indicia bearing strip at varying selected points intermediate the longitudinal edges thereof.
Claim 7
Dependent Claim
20 words
The indicating apparatus as claimed in claim 4 further comprising illuminating means adapted to provide illumination on said outermost surface.
Claim 8
Dependent Claim
24 words
The indicating apparatus as claimed in claim 1 wherein said driving means comprises an endless driving belt interconnecting said first and said second reels.
Claim 9
Dependent Claim
34 words
The indicating apparatus as claimed in claim 1 wherein said transport means are adapted to engage said first idler and a capstan turning at selected rotational speeds having said magnetically susceptible strip interposed therebetween.
Claim 10
Dependent Claim
26 words
The indicating apparatus as claimed in claim 1 wherein the width of said indicia bearing strip is unequal to the width of said magnetically susceptible strip.
Claim 11
Dependent Claim
59 words
The indicating apparatus as claimed in claim 1 wherein said indicia bearing strip has indicia thereupon depicted in a first quantity of horizontal tracks extending parallel to a longitudinal edge thereof, said magnetically susceptible strip having varying individualized magnetically encoded information tracks encoded in a second quantity of horizontal tracks thereupon, said first quantity unequal to said second quantity.
