A single-sided single-layer DVD-R has a storage capacity of about 4.7 Gbytes. When
a book has 700 double-byte characters that are printed per page, how many tens of
thousands of pages, at maximum, can be recorded on this DVD-R? Here, two bytes
are required to record one character, and only character information is stored. In
addition, 1 Gbyte is 1 billion (109) bytes.
