How the Default VariRec Setting Is Determined In most cases you don't have to worry about setting VariRec. First, we test many types of recordable DVD±R and CD-R media in our factory to determine the best write strategy (laser power and other factors) for that media. We include a table of the tested media and their write strategy in your drive's firmware. (This table is updated when you update your drive by downloading new firmware from the Plextor web site. ) 40 PX-712UF Installation and Users Manual Section 4. When you insert a recordable disc into your drive, Plextor's PoweRec technology automatically identifies the manufacturer, model, and special features of the media, then adjusts the laser power and writing speed so they're at the optimum settings for that disc. The drive uses OPC (Optimum Power Control) to further fine-tune the laser power setting to the specific disc that is in your drive. The combined values of the pre-defined write strategies, along with the OPC test results, create the default VariRec setting of zero. Changing the VariRec Setting VariRec lets you increase or decrease the laser power setting by up to 4 degrees in either the positive or negative direction. You can make these changes for DVD+R 4X and 2. 4X, DVD-R 4X and 2X, and CD-R 4X and 8X CD-DA/data writing. VariRec also lets you change the write strategy to match the dye profile of your disc. You can make these changes to do comparison testing with your DVD or CD player to find the setting that best suits you. Changing the laser power and write strategy changes the characteristics of the audio or data being written. For audio, you can hear these changes during playback, although what you hear will depend on speaker quality, audio settings, and environment. To use PlexTools Professional to change VariRec settings for writing: 1. To turn VariRec on for recording, place a check mark in the Enable VariRec box. Move the slider to adjust the laser power in either the plus or minus direction. PX-712UF Installation and Users Manual 41 Section 4.
