Web1 track holds 50 blocks 10 tracks (two for each platter), which is one cylinder holds 500 blocks. The file is 3750 blocks. Thus 3750/500 = 7,5 cylinders. So 8. 3. 1 block can hold 40 records. The disk has 50*1000*5 number of blocks (blocks per track * tracks * surfaces) Thus, this disk can store 40*50*1000*10 = 20M records. WebEach surface is divided into tracks (and sectors) in the same way. This means that when the head for one surface is on a track, the heads for the other surfaces are also on the corresponding tracks. All the corresponding tracks taken together are called a cylinder.
