Abstract
A method and system for transmitting tape cartridge information using a bi-axial tape cartridge antenna design. A contactless tape cartridge memory device is provided in which the memory device is accessible from multiple surfaces of the cartridge. A single flexible antenna surrounds the tape cartridge memory device. The antenna may be bent to fit within the corner of the tape cartridge, thus providing a parallel antenna surface to two locations on the cartridge, such as the front of the cartridge and the side or bottom of the cartridge. As a result, the memory device in the tape cartridge may be read when the cartridge is being inserted into the tape drive as well as while the cartridge is stored within the tape drive.
