In PPT

Ex 1

2000 tracks = 2000 cylinders

Ex 2

400 tracks = 40 cylinders

How it is possible? Why numbers of cylinders reduced?

Thank You

Ex1: 

2000 tracks PER SURFACE,  so there are 2000 cylinders

Ex2:

400 tracks are needed to store the file. Since the files are stored SEQUENTIALLY  and there are 10 surfaces, 100 cylinders are needed to store the file.
