ABSTRACT:
A magnetic read/write head suspension assembly and support roller particularly for use for recording and reading information on a magnetics-on-film (MOF) layer outside the image area of photographic filmstrips. The filmstrip is pressed against the support roller by upstream and downstream wrap rollers so that an angle of wrap over a predetermined length of the filmstrip in the filmstrip transport direction is achieved around the circumferential surface of the support roller that tends to flatten out cross film curl. Magnetic read/write heads are supported to bear against the edge regions of the filmstrip MOF layer opposite to the support roller and within the angle of wrap. The magnetic read/write heads are supported in a nesting VEE arrangement so that the head gaps can make a line contact of a predetermined head gap length extending in the direction of the filmstrip width. Edge guides track the filmstrip edges to position the magnetic read/write heads to follow the pre-recorded magnetic tracks at preset distances from the respective filmstrip edges.
