So in developing a system with high areal density and that resist external shock and disturbances, the essential mechanism is L/UL system. L/UL system has many benefits when applied to a small form factor (SFF) HDD. It allows for higher areal density increase since it is possible to reduce the flying height of slider and eliminate the texture zone that is used for parking for contact-start-stop systems. In addition, it allows for lower power consumption and prevents the head-slap between slider and disk during non-operating conditions.
