Heat resistant sensors equipped with any of a variety of transducers for measuring any of a variety of properties of fluids are constructed with components comprising materials that can withstand very high temperatures. Some embodiments of the sensors include a first pressure sensitive element and a second pressure sensitive element with respective first and second membranes positioned in juxtaposed relation to each other to form a capacitor. Some embodiments include a pusher that extends from the membrane toward a first electrode. Some embodiments have a housing comprising a ceramic substrate with a sensor element mounted on an inside surface of the substrate. Other embodiments have direction sensing capabilities including a heater positioned in a core material and at least three temperature sensors located at or near the peripheral surface of the core material and spaced apart angularly in relation to each other.

A method of writing servo patterns on a disc in a servo track writer includes sealing the STW to form an enclosed interior environment and then filling the STW with a low-density gas. Once the servo patterns are written to the disc, the low-density gas may be purged from the STW and recycled by directing the purged gas to a recovery system that separates the low-density gas from air. The disc may be preinstalled within a disc drive which in turn is loaded within the STW. Alternatively, the STW may comprise a multi-disc writer having a plurality of dedicated servo writing heads. The servo writer includes a cover having a sealable opening for loading either the disc drive in the STW or for loading a disc stack within the MDW.
