Abstract

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.

Disc Cartridge and Drive

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.

As shown in Fig. 1, a cartridge 1 is shown positioned next to a drive 2. The cartridge 1 includes a single disc (not shown) mounted for rotation within the cartridge. The drive 2 includes suitable head elements and a motor drive for rotating the disc. The drive 2 also includes a bezel 3 that includes an opening 4 with elongated notches 5 and 6. The opening 4 has a width such that the cartridge cannot be entered in a horizontal position. The cartridge 1 must be inserted at an angle to pass between elongated areas 5 and 6. As shown in Figs. 1 and 2, after the cartridge 1 is inserted into the drive 2, the cartridge can be rotated to a horizontal position. Ears 7 and 8 hold the cartridge into the drive 2 and prevent its removal except through rotation back into the ang...
