Abstract
Improved data protection features for a magnetic recording tape cartridge comprise a recess in the cartridge shell and a movable 'file protect' device, which may be a rotatable plug or slidable member. The features enable tape drives to distinguish between two types of cartridges with otherwise identical form factors, allowing one of the cartridges to contain a recording tape with different characteristics that require the tape drive to identify the characteristics of the tape prior to use.
