Abstract :
A method of producing a bit-patterned media on a flexible substrate using a low-cost, hot nanoimprinting process is investigated. Using a topographic master with features as small as 40 nm, a flexible plastic substrate is patterned with high fidelity. Magnetic material is sputter-deposited onto the patterned substrate to produce a magnetic tape media with densities as high as 100 Gigadot/in2. Magnetic recording characteristics of the coated bit-patterned tape is evaluated in an apparatus which slides a recording head on the media with a high-resolution positioning capability.
