Effects of Altitude on Thermal Flying-Height Control Actuation

Simulation of HAMR / Thermal Flying Height Control Sliders

Visual Control of Altitude in Flying Drosophila

Unlike creatures that walk, flying animals need to control their horizontal motion as well as their height above the ground. Research on insects, the first animals to evolve flight, has revealed several visual reflexes that are used to govern horizontal course. For example, insects orient toward prominent vertical features in their environment [1-5] and generate compensatory reactions to both r...

Contact and Temperature Rise of Thermal Flying Height Control Sliders in Hard Disk Drives

Contact behavior of thermal flying height control sliders and interfacial temperature rise upon head disk contact is investigated utilizing the resistance change of the read and write element. To achieve contact, the heater element of a TFC slider is energized with constant and square wave input profiles. To estimate the temperature rise during head disk contact, the resistance change of the re...

Numerical simulation of thermal flying height control sliders in heat-assisted magnetic recording

Heat assisted magnetic recording (HAMR) is one of the most promising techniques to extend the recording density in hard disk drives beyond 1 Tb/in. Although the diameter of the spot on the disk that is heated by the laser beam is very small, on the order of nanometers, high local temperatures on the disk and the heat dissipated in the slider during the light delivery process can cause thermal d...
