Abstract

A removable data cartridge is protected from air-transported particles such as dust, excessive moisture, contaminants, and the like by filtering or otherwise conditioning the airflow at initial startup. The recording media in the data cartridge is initially spun at a rate of speed higher than the operating speed for a brief period of time. By spinning the media at the increased speed, any particles in the cartridge will be removed by the filters. After the initial cleaning period, the spin speed of the media is reduced to a normal operating level.

Claims (7)

1. A method for removing particulates in particle laden air flow in a removable data storage cartridge, comprising:

rotating a storage medium at a first speed, wherein the first speed is higher than an operational speed of the storage medium;

while rotating the storage medium at the first, higher speed, filtering out particulates in particle laden air flow at a faster rate compared to filtering at an operational speed of the storage medium, the filtering being performed with one or more air processing units in the air flow without the one or more air processing units contacting the rotating storage medium; and

reducing the speed of the storage medium to a second speed, wherein the second speed is the operational speed of the storage medium.

2. The method of claim 1 , wherein the rotation of the storage medium induces the air flow over and beyond the rotating medium.

3. The method of claim 1 , further comprising rotating the storage medium at the first speed for a predetermined period of time.

4. The method of claim 1 , further comprising rotating the storage medium at the first speed upon insertion of the removable data storage cartridge into a drive.
