ABSTRACT:
A cartridge memory is diagonally placed so that two sides of a loop antenna of the cartridge memory are adjacent to two neighboring surfaces of a cartridge case. An external antenna has two tip portions adjacent to these two surfaces. Such an external antenna can enhance communication with a cartridge memory diagonally placed within a magnetic tape cartridge.
