Abstract

Diskettes collect dust (typically abrasive) when exposed in an industrial environment, even for the short period of time it takes to put them in the drive module. These abrasive particles cause wear of the media during normal operation of the diskette, to a point where it cannot be read properly, causing errors in the system. This type of error could effectively disable the system it is controlling and impact an entire assembly line. Previous solutions to this problem include creating a positive pressure inside the drive module, replacement of media at failure and protective envelopes for storage. The positive pressure approach is sufficient to exclude airborne dust from the head and drive area, but is not effective for cleaning particles attached to the diskette itself before it is introduced into the drive module.

Air-Jet Diskette Cleaner

Diskettes collect dust (typically abrasive) when exposed in an industrial environment, even for the short period of time it takes to put them in the drive module. These abrasive particles cause wear of the media during normal operation of the diskette, to a point where it cannot be read properly, causing errors in the system. This type of error could effectively disable the system it is controlling and impact an entire assembly line. Previous solutions to this problem include creating a positive pressure inside the drive module, replacement of media at failure and protective envelopes for storage. The positive pressure approach is sufficient to exclude airborne dust from the head and drive area, but is not effective for cleaning particles attached to the diskette itself before it is introduced into the drive module. Replacement of media at failure requires manual intervention. Therefore, it is undesirable, especially in automated systems, and lowers the overall reliability of the system it is controlling. Protective storage envelopes and boxes are typically used even in a controlled environment. This is still desirable in an industrial environment. However, it offers no protection to the media between storage and point of use. This new arrangement provides a more reliable method of preventing damage to magnetic media caused by particulate contamination at a comparable cost. Diskettes 10 are partially enclosed, being exposed at the head an...
