The measurements are taken with nominal power at sea level and 25°C ambient temperature. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions. • Average seek time is a true statistical random average of at least 5,000 measurements o

Seeking power and currents are measured during one-third-stroke buff- ered seeks. Read/Write power and current are measured with the heads on track, based on a 16-sector write followed by a 32-msec delay, then a 16-sector read followed by a 32-msec delay. Spinup power is measured from time of power-on to tim
