Abstract
Abstract A photographic filmstrip having a first recording area coated with transparent magnetic material superimposed on each frame and a second magnetic recording area coated with transparent magnetic material at a position outside of each frame. The border of the second recording area is pre-exposed so as to render the border visible by a developing process.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
A photographic filmstrip in which a photosensitive emulsion layer is formed on a first side of a base, and a plurality of images are sequentially taken on a plurality of frames defined on the photosensitive emulsion layer, comprising: a plurality of first recording areas positioned outside of each of said frames, information being magnetically recorded on at least one of said first recording areas; and indicating means for allowing visual recognition of each of said first recording areas.
Claim 2
Dependent Claim
78 words
A photographic filmstrip in which a photosensitive emulsion layer is formed on a first side of a base, and a plurality of images are sequentially taken on a plurality of frames defined on the photosensitive emulsion layer, comprising: a plurality of first recording areas positioned outside of each of said frames, information being magnetically recorded on at least one of said first recording areas; and indicating means for allowing visual recognition of each of said first recording areas.
Claim 3
Dependent Claim
23 words
A photographic filmstrip as claimed in claim 1, further comprising a positioning perforation formed in the filmstrip corresponding to each of said frames.
Claim 4
Dependent Claim
30 words
A photographic filmstrip as claimed in claim 1, wherein each of said first recording areas is formed on a second side, of said base, that is opposite said first side.
Claim 5
Dependent Claim
37 words
A photographic filmstrip as claimed in claim 3, further comprising a plurality of optically transparent second recording areas on which information is magnetically recorded, each of said second recording areas being superimposed upon one of said frames.
Claim 6
Dependent Claim
30 words
A photographic filmstrip as claimed in claim 4, wherein each of said first recording areas has one of optical density and color that is different from that of said base.
Claim 7
Dependent Claim
18 words
A photographic filmstrip as claimed in claim 4, wherein each of said first recording areas is optically transparent.
Claim 8
Dependent Claim
24 words
A photographic filmstrip as claimed in claim 6, wherein an outer periphery of each of said first and second recording areas defines a rectangle.
Claim 9
Dependent Claim
41 words
A photographic filmstrip as claimed in claim 7, wherein a contour line is recorded as a latent image, said contour line surrounds an outer periphery of said rectangle, said contour line being transformed into a visual image by a developing process.
Claim 10
Dependent Claim
41 words
A photographic filmstrip as claimed in claim 7, wherein L-character shaped corner marks are recorded as latent images at corners of said rectangle defined by second recording areas said corner marks being transformed into a visual image by a developing process.
Claim 11
Dependent Claim
31 words
A photographic filmstrip as claimed in claim 7, wherein the entirety of said rectangles defined by said first recording area, is pre-exposed so as to be visible after a developing process.
Claim 12
Dependent Claim
123 words
A photographic filmstrip in which a photosensitive emulsion layer is formed on a first side of a base, and a plurality of images is taken on a plurality of frames defined on the photosensitive emulsion layer at predetermined intervals, comprising: a plurality of first magnetic recording areas positioned outside of each of said frames, said first magnetic recording areas being coated with a transparent magnetic material, a border portion of each of said first recording areas being exposed so as to render said border portion visible by a developing process; a plurality of second magnetic recording areas coated with transparent magnetic material and superimposed upon each of said frames; and a positioning perforation formed on the filmstrip corresponding to each of said frames.
Claim 13
Dependent Claim
123 words
A photographic filmstrip in which a photosensitive emulsion layer is formed on a first side of a base, and a plurality of images is taken on a plurality of frames defined on the photosensitive emulsion layer at predetermined intervals, comprising: a plurality of first magnetic recording areas positioned outside of each of said frames, said first magnetic recording areas being coated with a transparent magnetic material, a border portion of each of said first recording areas being exposed so as to render said border portion visible by a developing process; a plurality of second magnetic recording areas coated with transparent magnetic material and superimposed upon each of said frames; and a positioning perforation formed on the filmstrip corresponding to each of said frames.
Claim 14
Dependent Claim
31 words
A photographic filmstrip as claimed in claim 11, wherein said first and second magnetic recording areas are formed on a second side of said base that is opposite said first side.
Claim 15
Dependent Claim
57 words
A photographic filmstrip as claimed in claim 12, further comprising: transparent third and fourth magnetic recording areas formed respectively on a leader portion and a trailer portion of the filmstrip, a border portion of each of said third and fourth magnetic recording areas being exposed so as to render said border portion visible by a developing process.
