FAQ for DVD/CD Media
DVD-R (hyphen R) media
|Do DVD-R media differ from DVD+R media?|
Both are recordable media, and are often called 'write once media.' (However, they do not record copyright protected data.)
[ Choose disc by LOGO ]
You can find which disc to use, DVD+R or DVD-R, from the logo marked on your drive or recorder.
[ For DVD recorder users ]
To record copy guarded digital broadcasts, CPRM media is necessary. Currently, there are no products compliant with CPRM in our product line-up. Please consult the manual of your recorder to see if it is compliant with the CPRM recording.
[ For DVD drive users ]When writing the data less than 1GB in compatible with DVD-Video(ROM) mode, there is a difference between DVD+R disc and DVD-R disc.
With DVD-R disc, when writing a data that is less than 1GB, addition to the actual data, the drive will write a dummy data until it reaches 1GB and then close the session. It will take a little longer time than writing the actual data.
With DVD+R disc, even the data you are going to write is less than 1GB, the session can be closed without writing the dummy data. You will be able to save a little time.
ex. Time difference when writing approximately 5 minutes DVD-Video type data (approximately 195MB). (8x disc and 8x drive used)
