Methods of measuring friction between a slider and ramp, and related systems
Measuring ramp friction in a disk drive including receiving a lift tab ramp load time profile for a voice coil motor and determining a load torque profile for a lift tab on the ramp based at least on the received ramp load time profile. The measuring also includes receiving a lift tab ramp unload time profile for the voice coil motor and determining an unload torque profile for the lift tab on the ramp based at least on the received ramp unload time profile. The measuring also includes calculating a ramp friction torque component based on the determined load torque profile and unload torque profile.
