The cells containing the magnetizable material to form the magnetic recording medium are covered by an additional layer of paper to protect and/or retain the magnetizable particles in place.
1 . A paper stock envelope having a body portion having an interior and a flap foldable over the body portion to effect closure of the interior of said envelope, comprising:
a magnetic recording medium extending over at least a portion of said envelope, said magnetic recording medium being retained within a plurality of interconnected depressions, indentations or cells formed as an integral part of the paper forming said envelope.
2 . The envelope of claim 1 which further includes an additional sheet of paper with said magnetic recording medium sandwiched between said additional sheet of paper and said cells.
3 . The envelope of claim 2 wherein said magnetic recording medium is contained in a plurality of discrete portions randomly disposed on said envelope.
4 . The envelope of claim 3 wherein said plurality of discrete portions are disposed on said body.
5 . The envelope of claim 3 wherein said plurality of discrete portions are disposed on said flap.
6 . The envelope of claim 3 wherein said plurality of discrete portions are disposed on said body and said flap.
7 . The envelope of claim 2 wherein said magnetic recording medium is contained in at least one measured and specifically placed portion of said envelope.
8 . The envelope of claim 7 wherein said measured and specifically placed portion comprises a continuous strip of magnetic recording medium extending along said body and said flap.
9 . The envelope of claim 7 wherein said measured and specifically placed portion comprises a continuous strip of magnetic recording medium extending along said flap.
10 . The envelope of claim 7 wherein said measured and specifically placed portion comprises a continuous strip of magnetic recording medium extending along said body and flap.
11 . An envelope as defined in claim 1 wherein said magnetic recording medium is overlappingly disposed on said body and said flap whereby recorded material in said overlap region is altered when said flap is opened.
12 . An envelope as defined in claim 2 wherein said magnetic recording medium is overlappingly disposed on said body and said flap whereby recorded material in said overlap region is altered when said flap is opened.
13 . The envelope of claim 7 wherein said measured and specifically placed portion comprises recording medium in a broken strip extending along said body.
14 . The envelope of claim 7 wherein said measured and specifically placed portion comprises recording medium in a broken strip extending along said flap.
