Preheating a hard disk drive head slider for head switch seek

摘要

Managing the flying height of a read-write head slider, such as in the context of a short or head switch seek, involves pre-heating the switched-to head while the active head is still performing a data read or write operation. Thus, both the active head and the switched-to head may be heated simultaneously, and once the switched-to head is switched to an active state upon the active head completing its corresponding operation, the switched-to head can immediately begin its operation with minimal or no further delay.
