Question:
Bits that Can Be Stored on the Disk
Background: I have a hard magnetic disk w/2 surfaces. The storage area on each surface has an inner radius of 1cm and and outer radius of 5cm. Each track holds the same number of bits even though the size differs from each other. The max storage density of the media is 10,000 bits/cm. The spacing between corresponding points on adjacent tracks is .1mm which includes the intertrack gap. The intersector gaps are negligible and that a track exists on the edge of the storage area. What is the max # of bits that can be stored on the disk and what is the data transfer rate from the disk to the head in bits per sec at a rotational speed of 3600 rpm? Thanks!!!
Update: We must assume that the intersector gaps are negligible and that a track exists on each edge of the storage area.
The book says the maximum storage density is 10,000 bits/cm.
I've typed all the info that I was given for the question. I hope you can help. Handwritten solution is acceptable.
