A magnetic disk drive rotates at 4000 rpm. What is the average rotational latency in milliseconds? (Hint: 1 second = 1000 milliseconds)
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.
