The 165th Topical Symposium of the Magnetic Society of Japan / The 28th Topical symposium of Nano-magnetics
Ultimate Magnetic Recording “Challenge to super terabit recording”
Various technology which aimed at the recording density of 1 terabit per square inch (1Tbit/in2) made a present target has been proposed to realize a hard disk drive (HDD) of large storage capacity. Last year, there were announcements the areal recording density of HDD achieved 612 Gbit/in2 and 803 Gbit/in2by present perpendicular recording system and by using a descrete track media. And it is expected that 1 Tbit/in2 will be realized within several years. To achieve an areal recording density of the super terabit, the ultimate technology which controls the nanometer and a nanosecond, in each technology like microfabrication, a smaller bit evaluation, and the local magnetization reversal, etc., is needed. The research on these is in progress.
In this joint symposium, researchers actively working in this field will give talks on their latest results and discuss methods realizing ultimate magnetic recording. We very look forward to your participation.
