    Consider a disk with the following characteristics (these are not parameters of any particular disk unit): block size B=1024 bytes, number of blocks per track=10, number of tracks per surface=400. A disk pack consists of 15 double-sided disks.

    (a) What is the total capacity of a track?
    (b) How many cylinders are there?
    (c) What is the total capacity of a cylinder?
    (d) What is the total capacity of a disk pack?

    (a) What is the total capacity of a track?
    total capacity of a track = block size*blocks per track = 1024*10 = 10240 bytes

    (b) How many cylinders are there?
    there are 400 cylinders because number of cylinders = number of tracks per surface

    (c) What is the total capacity of a cylinder?
    total capacity of a cylinder = 15*2*10*1024=307200 bytes

    (d) What is the total capacity of a disk pack?
    total capacity of a disk pack = total capacity of a cylinder*tracks per surface = 307200*400 = 122880000 bytes
