PC System with Reduced Flow of External Dust through Removable Media Drives

Disclosed is an invention to prevent the flow of dust through a diskette drive or another type of removable

media drive to reduce the potential for dust to gather and stick to the read/write heads in the drive. In

today's PC market, the diskette drive is the least used device shipped standard on a PC system. OS,

application program and device driver developers no longer distribute their products on diskette simply

because they are too small to hold the program code on a handful of diskettes. CD-ROMs currently are

the medium of choice for software distribution, with DVDs probably replacing CDs when DVD drives

become prevalent in the market place. A second favorite distribution is the internet with users

downloading software without ever having the software reside on any type of removable media.

Diskettes were also used in the past to exchange data between users. However, with the emergence

of the internet, emailing the data is far simpler and faster.

Taking into account the changes in the industry described above, diskette drives in a current PC system are rarely used. Because of the infrequent use, diskette drives are experiencing build up of dust on the diskette read/write heads. Users attempting to use their diskette drives on rare occasions are experiencing difficulty because the read/write heads are clogged and data can't be read from or written to the media. PC manufacturers are having to help customers by recommending or supplying diskette head cleaning material and cleaning instructions in order to remedy the situation.

Contributing to the problem is the cooling schemes used in PC systems. The cooling subsystem draws external air into the system enclosure through the system openings in order to cool the system. The air is exhausted through another system enclosure opening or the power supply. The system openings include openings in the enclosure specifically intended for cooling purposes and openings in the removable media devices which have openings to receive media but not relied upon for cooling. Hence the air flow from outside to inside the enclosure is used to cool the system internals also unintentionally draws external air through these removable media devices. This unintentional flow of air through the drives also draws outside dust into the drives. Compounding the flow of extra dust through the drive is the fact that diskette drives are infrequently used and therefore accounts for the buildup on the read/write heads. Otherwise, if the drives were frequently used, the dust would be knocked off the read/write heads and more than likely problems described above would not be encountered. This invention helps red...
