What is the approximate time required to access the following sectors, assuming that a new seek is not required if successive sectors are on the same track and the difference between sector numbers is greater than 1? The following data is presented as (t,s), where t is the track number and s is the sector number. (12,25), (12,27), (12,39), (12,40), (13,90), (11,108), (26,25), (26,24), (200,19) For each seek there is a track step time and a rotational latency. The rotational latency is one half of a revolution, or ½ x 1/120s = ½ x 8.333ms = 4.1667 ms
