This study aims to investigate the impact that factors such as skew, radius, and transition curvature have on areal density capability in heat-assisted magnetic recording hard disk drives. We explore a “ballistic seek” approach for capturing in-s

System-level requirements for heat-assisted magnetic recording at high areal density are presented in this article. The primary factors that affect bit error rate (BER) are spatial, or media, signal-to-noise ratio (SNR), reader SNR, and channel bit d

The areal density achievable with heat-assisted magnetic recording (HAMR) is directly related to the temperature gradient produced in the recording media by the near-field transducer. The thermal gradient in the down track direction affects the linea

In an ideal magnetic recording system, individual bits would be recorded as rectangular magnetic domains in the recording media, but in reality, the transitions from one bit to the next are curved due to practical geometry considerations. This is par

Curvature of recorded bit and skew are two factors limiting further improvement of the areal density capacity of heat-assisted magnetic recording. Performance degradation due to curvature and skew is evaluated using micromagnetic modeling and spin-st

The downtrack thermal gradient (DTTG) is a key metric determining the performance of heat-assisted magnetic recording heads. It describes the change in temperature with respect to the position at the recording point, which determines the transition w
