In order to ensure that a cartridge is inserted correctly into its drive, at a required angle to clear the internal functions such as read/write heads, the opening into the bezel are offset such that the opening is too small to insert the cartridge in a horizontal position. The cartridge must be entered at an angle between the elongated portions of the bezel and rotated horizontal into the operating position. The cartridge is captured behind ears on the bezel to ensure that the cartridge cannot be removed until correctly rotated back to its inserted angle. The cartridge is designed for free rotation of a disc, internal to the cartridge, while providing a handle and label areas.
