Roll stabilized, nesting vee, magnetic head assembly for magnetic-on-film

摘要

An apparatus for reading and/or writing information on the magnetic surface of a photographic filmstrip. The apparatus includes a mounting member and a fixed support roller over which a filmstrip is passed. The roller has an axis of rotation. At least one magnetic head (20) is mounted to the mounting member in a manner such that the head comes in contact with the filmstrip (44) over the area which the film is in contact with the fixed support roller (28) at a first point along the circumference of said support roller. The mounting member has a contact surface for coming in contact with the filmstrip (44) at a second area in which the filmstrip is in contact with the support roller which is located at a second point spaced circumferentially from the first point. Biasing means, such as a spring (55), is provided for applying a force against the mounting member so as to cause the at least one magnetic head (20) and the at least one contact surface to be pressed against said film and support roller simultaneously such that the mounting member will be nested against the support roller. <IMAGE>
