The time required to spin the desired sector under the read/write head

1.	The time required to spin the desired sector under the read/write head, once the read/write head is positioned on the desired track.(a) Seek time(b) Arrival rate(c) Latency(d) Transfer rateThis question was addressed to me in semester exam.Query is from Magnetic Disks topic in chapter Secondary Storage Devices of Computer Fundamentals
Answer» Correct choice is (c) LATENCY For explanation: It is CALLED latency. It is one of the factors on which the DISK access time DEPENDS. Disk access time is the interval between the instant a request is made and the instance OPERATION is completed.
