Abstract
Media (31) for use in a magnetic tape drive (30) has a magnetic recording/reproducing segment (3106) for magnetically transducing information; a cleaning segment (3104); and, an identification window segment (3108). The identification window segment is situated intermediate the magnetic recording/reproducing segment and the cleaning segment, and has an electromagnetic transmissiveness which differs from the magnetic recording/reproducing segment and the cleaning segment. Preferably, the identification window segment is transparent to a predetermined wavelength range (e.g., infrared) while the magnetic recording/reproducing segment and the cleaning segment are opaque to the same predetermined wavelength range. The identification window segment has a dimension (e.g., length L) chosen to provide a predetermined media or cartridge signature when the media is transported at a selected linear velocity.
