Abstract:
A TAMR (thermal assisted magnetic recording) equipped DFH (dynamic flying height) type slider ABS design, when operating in a HDD (hard disk drive) produces exceptional low pressure/stiffness for improved touch down detection and back-off efficiency as well as wear and damage reduction due to the improved capabilities as well as reduction in heat transfers. The supplementation of the slider with multiple heaters, three herein, disposed about the write-head in the cross-track direction provides the slider with enhanced dynamic stability that would normally not be achievable with the exceptional low pressure/stiffness.
