•   The effect of head field gradients and thermal gradients in heat assisted magnetic recording is investigated. When recording at a constant temperature, or in a constant external field, clear correlations between the recording performance and the head field gradient or thermal gradient can be found. Thermally assisted recording with a write head is much more complex and higher gradients do not necessarily translate into higher SNR.
