Abstract A magnetic reading and/or recording apparatus for reading and/or recording information from/on a magnetic information track on a photosensitive medium includes a magnetic reading and/or recording element connected to an edge follower having a variable tracking position. The edge follower tracks a longitudinal edge of a moving photosensitive medium by adjusting with the photosensitive medium responsive to any departures of the photosensitive medium from a defined path to effect a constant orientation of the magnetic reading and/or recording element with respect to the longitudinal edge of the photosensitive medium. The magnetic reading and/or recording apparatus further includes a member supporting the edge follower for movement by a forward leading edge of a photosensitive medium, when the photosensitive medium enters the defined path, from a normal initial position in the defined path to the variable tracking position, to effect a proper relation between the photosensitive medium in the defined path and the edge follower in its variable tracking position.
A web guiding device for use in a magnetic reading and/or recording apparatus, said web guiding device comprising: means defining an entrance for accepting a web; means for guiding a longitudinal edge of a web; and means for supporting said guiding means to cause said guiding means to pivot about a point remote from a center point of said guiding means between a first position parallel to a longitudinal edge of a web and a second position angled towards said entrance when a leading edge of a web enters a magnetic reading and/or recording apparatus, said point about which said guiding means pivots being included in a plane which is perpendicular and transverse to said web, and which intersects said guiding means.

A web guiding device for use in a magnetic reading and/or recording apparatus, said web guiding device comprising: means defining an entrance for accepting a web; means for guiding a longitudinal edge of a web; and means for supporting said guiding means to cause said guiding means to pivot about a point remote from a center point of said guiding means between a first position parallel to a longitudinal edge of a web and a second position angled towards said entrance when a leading edge of a web enters a magnetic reading and/or recording apparatus, said point about which said guiding means pivots being included in a plane which is perpendicular and transverse to said web, and which intersects said guiding means.
Claim 3
Dependent Claim
27 words
A web guiding device as defined in claim 1, wherein said supporting means includes a member having at least one pointed end which contacts said guiding means.
Claim 4
Dependent Claim
78 words
The web guiding device as defined in claim 1, further comprising: a magnetic reading and/or recording element for reading and/or recording information from/on a magnetic information track on said web, said magnetic reading and/or recording element being connected to said guiding means, said web including a photosensitive medium, when said guiding means is in said first position a constant orientation of said magnetic reading and/or recording element with respect to the longitudinal edge of the web is maintained.
