Abstract
Abstract A magnetic reading and/or recording apparatus includes a plurality of magnetic reading and/or recording elements to read and/or record information from/on a flexible magnetic recording material and a flexible plate having several cut-outs arranged to define individual flexible sections of said plate between respective pairs of said cut-outs. The magnetic reading and/or recording elements and the flexible plate are arranged to position the flexible sections of the plate to support respective flexible sections of the flexible magnetic recording material substantially in contact with the magnetic reading and/or recording elements.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A magnetic reading and/or recording apparatus comprising: a plurality of magnetic reading and/or recording elements to read and/or record information from/on a flexible magnetic recording material; a flexible plate having several cut-outs arranged to define individual flexible sections of said plate between respective pairs of said cut-outs; and means for arranging said magnetic reading and/or recording elements and said flexible plate to position said flexible sections of said plate to support respective flexible sections of a flexible magnetic recording material substantially in contact with said magnetic reading and/or recording elements.
Claim 2
Dependent Claim
90 words
A magnetic reading and/or recording apparatus comprising: a plurality of magnetic reading and/or recording elements to read and/or record information from/on a flexible magnetic recording material; a flexible plate having several cut-outs arranged to define individual flexible sections of said plate between respective pairs of said cut-outs; and means for arranging said magnetic reading and/or recording elements and said flexible plate to position said flexible sections of said plate to support respective flexible sections of a flexible magnetic recording material substantially in contact with said magnetic reading and/or recording elements.
Claim 3
Dependent Claim
27 words
A magnetic reading and/or recording apparatus as defined in claim 1, wherein said arranging means includes a mounting block having a recess to accept said flexible plate.
Claim 4
Dependent Claim
59 words
A photographic apparatus comprising: a plurality of magnetic reading and/or recording elements to read and/or record information from/on a flexible photographic material; and a flexible plate having a plurality of individual flexible segments each positioned to independently bias respective flexible sections of a flexible photographic material substantially into contact with different ones of said magnetic reading and/or recording elements.
Claim 5
Dependent Claim
59 words
A photographic apparatus comprising: a plurality of magnetic reading and/or recording elements to read and/or record information from/on a flexible photographic material; and a flexible plate having a plurality of individual flexible segments each positioned to independently bias respective flexible sections of a flexible photographic material substantially into contact with different ones of said magnetic reading and/or recording elements.
Claim 6
Dependent Claim
61 words
A photographic apparatus as defined in claim 3, further including a resilient pad located adjacent said flexible plate on a side of said plate opposite a side adjacent to a flexible photographic material, and means for applying discrete amounts of pressure along said resilient pad to insure a uniform interface between the photographic material and said magnetic reading and/or recording elements.
Claim 7
Dependent Claim
38 words
A photographic apparatus as defined in claim 3, further including means for automatically adjusting said flexible plate in a roll axis to insure a uniform interface between said magnetic reading and/or recording elements and a flexible photographic material.
Claim 8
Dependent Claim
50 words
A photographic apparatus as defined in claim 5 wherein said adjusting means includes a mounting block having a recess to accept said flexible plate and having opposite edges located on a lower portion of said mounting block, and a loading spring positioned across said opposite edges of said mounting block.
