Approximately how many times can a
DVD-RW or DVD+RW disc be rewritten?
- 1000 times
- 10 times
- 100 times
- 1 time
EXPLANATION
As is the case with other optical
storage media using phase-change technology there is a limit to the number of
times the recording layer in a DVD-RW, DVD+RW and DVD-RAM disc can be reliably
switched between its crystalline and amorphous states.
It is estimated that a
DVD-RW or DVD+RW disc can be rewritten approximately 1000 times and a DVD-RAM
100,000 times. In addition, these formats (under certain circumstances) employ
defect management schemes to actively verify data and skip over or relocate
problems to a spare area of the disc.
