A hypothetical disk drive has the following properties.

Rotational speed Sectors/track Track-to-track seek times 7,200 rpm 256 2 ms 1 ms 0.4 ms Tracks stepped < 10

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 tis the track number ands is the sector number.

(12,25), (12, 27), (12, 39), (12, 40), (13, 90), (11, 108), (26, 25), (26, 24), (200, 19)
