<*1> Under the condition of normal voltage, 25oC normal temperature and bottom side down.
<*2> Average time to seek all possible adjacent track without head switching.
<*3> Weighted average time to travel between all possible combination of track calculated as below.
Weighted average access time = [ Sum of P(n)*t(n) ] / [ Sum of P(n) ], n = 1 to N.
Where, | N ; Total number of tracks. |
P(n); | Total number of seek for stroke n [ = 2*(N - n) ]. |
t(n); | Average seek time for stroke n. |
Average seek time to seek to stroke n is the average time to 1,000 seeks for stroke n, with random head switch.
<*4> Average time for 1,000 full stroke seeks with random head switches.
<*5> Typical values are for the condition of normal voltage, 25oC normal temperature and placing bottom side down. Maximum values are for all conditions specified in this document.
