Tape and cassette for cleaning magnetic recording heads

Claim 2

A tape cassette, having a generally hollow case and a pair of tape reels rotatably mounted therein, for use in a recording and reproducing apparatus having a magnetic head adapted to be engaged with tape in the cassette, wherein the improvement comprises a magnetic head cleaning tape having its opposed ends respectively secured to said reels for winding thereon, said tape having a base formed of non-woven fibrous material and a woven scrim of widely spaced reinforcing threads which project from at least a surface of said base which contacts said magnetic head for engaging and removing dust particles and the like from the head and wherein said reinforcing threads include a first set of threads extending across the width of said tape and slightly pitched with respect thereto such that at least two of said first set of threads are engaged with said magnetic head during the cleaning operation.

Claim 3

The tape cassette as defined in claim 1 including a second set of threads extending substantially transversely to said first set and at a slight angle to the longitudinal axis of the tape.

Claim 4

The tape cassette as defined in claim 2 wherein the pitch between the threads in said first set is between 2.5 and 5.0 mm.

Claim 5

The tape cassette as defined in claim 3 wherein the pitch between said second set of threads is approximately 2.5 mm.

Claim 6

A cleaning tape for use in recording and reproducing equipment having a magnetic head, said tape comprising an elongated base formed of non-woven fibrous materials and a reinforcing scrim having relatively widely spAced threads secured to at least one side of said base, said tape being adapted to engage the magnetic head in said recording and reproducing apparatus along said one side of said base for wiping said magnetic head to remove dust or the like therefrom, wherein said scrim includes first and second sets of threads on said one side of said tape which is adapted to be engaged with said magnetic head, said first set of threads being substantially parallel to each other and extending across the width of said tape and being slightly pitched with respect thereto, said second set of threads being substantially parallel to each other and extending substantially transversely to said first set and at a slight angle to the longitudinal axis of the tape, said threads forming projections on said one side of the tape for engaging and removing dust particles and the like from said magnetic head.

Claim 7

A cleaning tape for use in recording and reproducing equipment having a magnetic head, said tape comprising an elongated base formed of non-woven fibrous materials and a reinforcing scrim having relatively widely spAced threads secured to at least one side of said base, said tape being adapted to engage the magnetic head in said recording and reproducing apparatus along said one side of said base for wiping said magnetic head to remove dust or the like therefrom, wherein said scrim includes first and second sets of threads on said one side of said tape which is adapted to be engaged with said magnetic head, said first set of threads being substantially parallel to each other and extending across the width of said tape and being slightly pitched with respect thereto, said second set of threads being substantially parallel to each other and extending substantially transversely to said first set and at a slight angle to the longitudinal axis of the tape, said threads forming projections on said one side of the tape for engaging and removing dust particles and the like from said magnetic head.

Claim 8

The cleaning tape as defined in claim 5 wherein said first and second sets of threads are woven.

Claim 9

The cleaning tape as defined in claim 6 wherein the pitch between the threads in said first set is between 2.5 and 5.0 mm.

Claim 10

The cleaning tape as defined in claim 7 wherein the pitch between said second set of threads is approximately 2.5 mm.

Claim 11

The cleaning tape as defined in claim 8 wherein said non-woven base and said threads are formed of nylon or rayon.
