More than 100 years projectedlifetime for DVD-R General

This statement refers to DVD-R forGeneral media made by members of the DVD Application Group. These disks aremade under best quality control using only the best materials available.Therefore these media enjoy excellent recording quality and archival stability.

Sample disks underwent a strict qualitytest in climate controlled environment for estimation of the lifetime of ourDVD-R products. The approven statistical Arhenius method was used to get the results.The test method and tests results are shown below.

Test Method:

1. Record data at normal officeenvironment and measure PI Error Rate.

PI Error Rate is specified as below 280 in the specifications.

2. Put media into a climate controlledenvironment which is set to the following

conditions:

Temperature Humidity

Oven 1 80 degree 85% RH

Oven 2 70 degree 85% RH

Take the media out of the oven atdefined intervals and measure PI error.

3. When PI Error exceeds 280, that timeis defined as the end of life at that

temperature.

4. Apply “Arhenius”method to project life at the office environment
