Patterned medium for heat assisted magnetic recording
Heat assisted magnetic recording HAMR is a potential solution to extend the limits of conventional magnetic recording. In HAMR, the heating of the recording medium is achieved with a near-field optical transducer. Although the literature suggests novel transducers, there is little consideration of the optical and thermal aspects of the magnetic medium. In this letter we suggest a recording medi...
متن کاملExperimental estimates of in-plane thermal conductivity in FePt-C granular thin film heat assisted magnetic recording media using a model layered system
Cross-plane thermal conductivity kth measurements of vertical stacks of FePt/C were used to estimate the in-plane thermal conductivity of Heat Assisted Magnetic Recording (HAMR) media that consist of columnar FePt grains segregated by thin C grain boundaries. FePt/C multilayers with varied repeat units and FePt layer thicknesses (chosen to represent HAMR media grain sizes) were measured using F...
متن کاملMgO seed layers for CoCrPt/Cr longitudinal magnetic recording media
Sputter deposited MgO thin films with the B1 crystal structure and ~002! film texture are used as seed layers to improve the texture and magnetic properties of the CoCrPt/Cr magnetic thin films on glass substrates for longitudinal recording. The desired ~002! textured Cr underlayers are usually obtained by sputtering Cr onto heated substrates. However, it is found that the MgO seed layers can i...

متن کاملSignal Processing for Bit-Patterned Media and Heat-Assisted Magnetic Recording Systems with Media Noise
With the advent of the information age, the demand for larger storage capacity is ever increasing. However, the need to continue scaling conventional magnetic recording technologies to higher areal densities has led to physical and engineering limits which are difficult to overcome. New magnetic recording technologies are required. Bit-patterned media recording (BPMR) and heat-assisted magnetic...
