Verbatim DVD-RW 4x

Sony DW-Q28A

This is going to be the last disc we will discuss today.

As in all the previous cases the results obtained with the Sony drive do not leave us any causes for concern. The PIE and PIF error rates are much lower than the allowed maximums, as to ECMA. All the errors are spread evenly over the disc surface, with a little bit higher error density in the end of the disc.

The disc surface scans are really impressive and indicate excellent disc quality. The maximum number of 9 PI Failures was recorded only once, and hence should be regarded as an exception, rather than a rule.
