Consider a disk pack with a seek time of
20 micros seconds and a rotational speed of
1000000 rotations per minute (RPM). It has
1200 sectors per track and each sector can
store 512 bytes of data. Consider a file stored in
the disk. The file contains 8000 sectors. Assume
that every sector access necessitates a seek,
and the average rotational latency for accessing
each sector is half of the time for one complete
rotation. The total time (in microseconds)
needed to read the entire file is
