Abstract

Disclosed is a device that increases the operational life of a tape drive's door mechanism. The device protects the door in high speed cartridge insertion environments. A key advantage to the device is that it can be easily factory and field installed in only those environments that require it. Refer to the following figure for the numbered items. The initial sequence of a tape drive's operation consists of inserting a data storage cartridge #2 into the drive's loader #4. Data is then read from or written to the storage media in the cartridge. This device reduces damage to a loader's door assembly by using a mechanism #1 to hold the loader's door #3 partially open. The partially open door is then at an angle from its normal vertical position. Due to the door's inclination caused by mechanism #1, a high speed cartridge #2 insertion transmits much less force to the loader's door at #3. Mechanism #1, also called a fiducial, is also only used by high speed automated cartridge insertion equipment to locate the correct position to insert the cartridge. Thus, this invention adds high speed impact protection to the door #3 only when the tape drive is operating in a high speed cartridge insertion environment. #3 Door #1 Fiducial

A fiducial that extends a tape drive's loader door life

Disclosed is a device that increases the operational life of a tape drive's door mechanism. The device protects the door in high speed cartridge insertion environments. A key advantage to the device is that it can be easily factory and field installed in only those environments that require it.

Refer to the following figure for the numbered items. The initial sequence of a tape drive's operation consists of inserting a data storage cartridge #2 into the drive's loader #4. Data is then read from or written to the storage media in the cartridge.

This device reduces damage to a loader's door assembly by using a mechanism #1 to hold the loader's door #3 partially open. The partially open door is then at an angle from its normal vertical position. Due to the door's inclination caused by mechanism #1, a high speed cartridge #2 insertion transmits much less force to the loader's door at #3. Mechanism #1, also called a fiducial, is also only used by high speed automated cartridge insertion equipment to locate the correct position to insert the cartridge. Thus, this invention adds high speed impact protection to the door #3 only when the tape drive is operating in a high speed cartridge insertion environment.
