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

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

Differences between heat-assisted magnetic recording (HAMR) and conventional perpendicular magnetic recording at narrow track widths are compared. We can see that HAMR appears to have similar adjacent track interference, but increased readback signal

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
