Scratch-proof DVDR
|
| Recently, a lot of DVD-R disks with hard coat are put on the market. The little child will damages disks by carelessly touching. So, we are helped very much by hard coat. Then, now I test which "hard coated disk" is most excellent? |
|
[1]. At first, burn disks with pioneer DVR-A12, and scan PI/PIF rate with pxscan, [2]. Put the disk(face recording side to the ground) on the finest sandpaper, put a weight on the disk, and drag the disk horizontally. [3]. Scan PI/PIF rate again. Next, repeat [2] process with more heavy weight.  (DVD-R has the rib in the inner. Sandpapers are set to avoid it.)  |
