Load/Unload (L/UL) is an alternative to contact start-stop (CSS) technology which eliminates stiction and wear failure modes associated with CSS. Other benefits of L/UL include increased areal density due to smooth disk surfaces, thinner overcoats and lower head flying height; improved shock resista...
