A tape cartridge has a front face sized for compatibility with an industry standard tape drive, and has sides longer than the sides of some industry standard cartridges. The sides and top of the housing extend outwardly in width to form a back portion of the cartridge that is wider than the front portion and prevent the cartridge from being inserted into non-compatible tape drives. Two large diameter tape hubs improve the empty hub to full pack diameter ratios, and improve the resulting tangential drive force and tape tension profiles as the tape moves between the hubs. Flanges are permanently bonded to the hubs to prevent the tape packs from shifting and a spring biases the hubs against the baseplate. A back set of rollers includes a high-drag roller that engages the drive belt at a fixed wrap angle and produces a relatively constant drag. A front set of rollers includes a drive roller and has rollers mounted to form substantially equal geometries with rollers in the back set respective to the tape hubs.

A access control system includes a catch configured to be affixed to an inner portion of an enclosure, a latch configured to engage the catch when the catch is attached to the enclosure and an access door of the enclosure is in a closed position. The access control system is configured to detect, using one or more sensors, when the latch is within a predetermined proximity of the catch, and responsive to detecting that the latch is not within the predetermined proximity of the catch, determine whether an authorized credential was received via a communication interface to open the latch, and when the authorized credential was received, register an authorized opening of the latch in a memory device, and when the authorized credential was not received, register an the unauthorized opening of the latch in the memory device and enter an alert state.
