The time taken for the read/write head to move to the correct track on the magnetic disk is called (A) Approach time (B) Seek time (C) Epoch delay (D) Latency delay
Data bit recording in magnetic discs is based on which property of magnetic material? Please explain. Is it a problem if this feature is too large? Why is that? A disk drive is provided that can write data at a flux change rate of 6 million per second. Calculate the maximum number of data bytes that can be stored in one ring of the disk when the disk is rotated at 6000 rpm. Indicate how the increase in disk rotation speed affects the data storage capacity.

What is the average time to read or write a 512-byte sector for a typical disk rotating at 45,000 RPM? The advertised average seek time is 2 ms, the transfer rate is 400 MB/sec, and the controller overhead is 0.2 ms. Assume that the disk is idle so that there is no waiting time.
