Technical Notes
CD-R/RW drives are equipped with a buffer memory, which temporarily stores
data that is being transferred. When the buffer memory becomes empty due to a
delay of data transfer for any reason, a writing error happens. Such condition is
defined as buffer underrun, and such an error is defined as a buffer underrun
error.
Buffer Underrun Protection is featured in the CRW3200UX drive.
When buffer underrun almost happens, Buffer Underrun Protection temporarily
suspends the writing process. Writing resumes when enough data has
accumulated in the buffer memory. Buffer Underrun Protection in the
CRW3200UX drive is extremely accurate, resulting in seamless recording
before and after suspension.
Test writing
Test writing is a function to check for the possible occurrence of buffer underrun in
your computer environment. When Buffer Underrun Protection of the CD writing
software is activated, the test writing function cannot be operated. Buffer Underrun
Protection should be deactivated to operate the test writing function.
