Shape Memory Alloys (SMAs) are well suited for use as linear actuators. In particular, NiTi wires as linear SMA actuators offer the advantages of light weight, a simple actuation mechanism and high force-to-weight ratio. An additional advantage is that the electrical resistance of the NiTi wires varies intrinsically as the material undergoes a phase change(More)
We present the results of a simulation study of applying turbo decoding to optical data storage channel in the presence of transition noise. We use an optical recording channel model that captures the storage density effects, the effects of transition noise, the effects of finite equalizer lengths and the noise coloring caused by the equalizers. Our(More)
We have made significant progress towards achieving 100 Gb/in/sup 2/. We have designed and fabricated a super-solid immersion lens (SIL), implemented a new spot size measurement technique capable of measuring very small near-field spots, fabricated centre aperture detection magnetic super resolution (CAD-MSR) media and demonstrated turbo coding for ultra(More)
