“…DTR disks were fabricated by nano-imprint lithography (NIP) (Wachenschwanz et al 2005). The magnetic layer (20 nm), the diamond like carbon (DLC) layer (2 nm), and the lubricant film (1.2 nm) were deposited after nanoimprinting.…”

The contact deformation and wear characteristics of smooth and discrete track recording (DTR) media are investigated using nano-indentation and nano-scratch testing. Plastic deformation of the land areas between adjacent grooves was found to be substantially larger than in the smooth regions of the same disk. Reciprocating wear tests showed that wear was more severe for discrete track disks than for smooth disks. To improve the tribology of DTR media, planarization of discrete track disks appears to be necessary.

“…In DTR, adjacent tracks are separated from each other by circular ''grooves'' causing a reduction in ''cross-talk'' and an improvement in the signal to noise ratio (SNR) (Wachenschwanz et al 2005). DTR technology has the potential of achieving areal densities in excess of 1 Tbit/ in 2 .…”

An analytical model for the read back signal is derived for perpendicular and longitudinal magnetic recording. The model captures the contribution of a single bit rather than the contribution of a bit transition which makes it applicable to patterned media as well as continuous media. It is based on the law of Biot-Savart and separates the contribution of the magnetic media from the head sensitivity function.

“…Several investigations have been published that discuss the head/disk interface for patterned media. Wachenschwanz et al [2] reported an increase in the signal to noise ratio (SNR) and a better write efficiency for discrete track type of patterned media. Head/ disk interfaces for patterned media are complicated to manufacture and pose challenging problems from a tribological viewpoint.…”
