The data density of a Blu-ray disk using a 405-nm laser is 1.5x107 bits nm-2. Disks have an outside diameter of 120nm and a hole of 15-nm diameter. How many data bits can be contained on the disk? If a Blu-ray disk can hold 9,400,000 pages of text, how many data bits are needed for a typed page? (hint: determine the area of the disk that is available to hold data. The area inside a circle is given by A=r2, where the radius r is one-half of the diameter.)
