Abstract
A scanner transfers information in the form of magnetic characters to a soft magnetic film, and subsequently transfers the information to a storage medium, such as disc, tape, or the like. Use of amorphous and other bubble material is suggested. A bias field is coupled through the magnetic characters to the material in which bubbles are generated and transported.
