Abstract
An apparatus for reducing head wear in a helical scan tape transport passes a flow of relatively clean, dry air through a transport housing without allowing the flow of air to flow directly across the rotary head assembly. Air from a fan positioned at a rear portion of the transport cools a power supply and creates a positive air pressure within the transport housing. The air is heated by the power supply before it passes through the transport housing, so that only relatively 'dry' air reaches the rotary head assembly. The air is exhausted out the opening through which a tape is loaded. This arrangement substantially reduces the possibility of contaminants entering the transport housing. Additionally, the air cleans a magnetic recording tape on a tape cartridge as the tape is passes through the transport housing so that only relatively 'clean' tape reaches the rotary head assembly.
