ABSTRACT:
In an illustrated embodiment a magnetic transducing system utilizes a short length of magnetic tape as an electronic image store. The magnetic tape is held in an arcuate loop configuration by means of an air cushion at the periphery of a rapidly rotating cylinder. The magnetic head or heads may rotate at the same rotational rate as the cylinder and scan along the inner side of the tape loop with essentially zero contact pressure, the tape being free of guiding means at its outer side except at its entrance point to the loop, and having a trailing free end slightly spaced from the entrance point. A cartridge may supply a length of magnetic tape approximately equal to the circumference of the cylinder to the system for a transducing operation and then rewind the tape for protected storage.
