Solution(By Examveda Team)
The advantage of suing multiple heads on each movable access arm in reduced seek time. Seek time is the time required to move the disk arm to the required track. Rotational delay or latency is the time it takes for the beginning of the required sector to reach the head. Sum of seek time (if any) and latency is the access time.Related Questions on Computer Fundamental Miscellaneous
