A disk consists of two thousand concentric tracks. The disk is 5.2 inches in diameter. The innermost track is located at a radius of 1/2 inch from the center. The outermost track is located 2 1/2 inches from the center. The density of the disk is specified as 1630 bytes per inch along the track. The transfer rate is specified as 256,000 bytes per second. The disk is CLV. All blocks are of equal size.

a. The innermost track consists of ten blocks. How many bytes are contained in a block?
b. How many blocks would the outermost track contain?
c. The capacity of the disk is approximately equal to the capacity in bytes of the middle track times the number of tracks. What is the approximate capacity of the disk?
d. What is the motor rotation speed when reading the innermost track? The outermost track?
