Influence of Parasitic Capacitance on Single and Dual 2-D Magnetic Recording Read Head Performance

Tuning coercive force by adjusting electric potential in solution processed Co/Pt(111) and the mechanism involved

“…However, due to problems associated with increasing the storage capacity of hard disk drives, the data storage community faces the necessity of exploring and developing new concepts in attempts to increase areal density 1 2 3 . In recent years, extensive efforts have been devoted to exploring alternate approaches for improving the storage density of magnetic recording devices, and include two-dimensional magnetic recording (TDMR) 4 5 , heat-assisted magnetic recording (HAMR) 6 7 8 9 , microwave-assisted magnetic recording (MAMR) 10 11 , bit-patterned magnetic recording (BPMR) 12 13 14 15 , and optical switching of magnetic domains 16 17 18 . For instance, a broadband near-field thermal extraction device based on hyperbolic metamaterials can significantly enhance near-field energy transfer by extracting evanescent waves with arbitrarily large lateral wave vectors 6 .…”
