Title Proper : Exchange Coupled Composite Media For Perpendicular Magnetic Recording
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Supperparamagnetism is the fundamental factor that limits the achievable arealdensity in magnetic recording. Materials with extremely high magnetic anisotropy haveto be used for recording media to obtain thermally stable data storage. However, therequired writing field will be a serious problem for the recording media with extremelyhigh anisotropy. Conventional perpendicular magnetic recording partially alleviates thisproblem by applying a soft underlayer. Due to the limitation of available materials withhigh saturation magnetization, the maximum writing field available is around 2.45 T.This will limit the attainable recording density to 500 ~ b i t / i n ~ , which will be reachednear the end of the first decade in this new century. In order to continue the success of...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
