• The effects of E-block arm thickness on the head off-track vibration and the airflow in a modeled hard disk drive were investigated experimentally. Four arms with different thicknesses were tested. The Power spectra of the head vibrations were measured using laser Doppler vibrometry (LDV), and were used to compute the rms off-track vibrations and their components over selected frequency bands. The mean speed and flow fluctuation power spectra of the airflow downstream of the arm tip were measured using constant-temperature hot-wire anemometry (CTA), and these measurements were used to compute the rms dynamic head fluctuations and their components in the measurement region. A positive correlation was observed between the dynamic pressure fluctuation levels and the vibration levels.
