New SuperDrives support Double-Layer DVD burning
The new SuperDrives built into the Power Mac G5 (Early 2005), iMac G5 (Ambient Light Sensor) computers, and eMac (Early 2005) computers now support DVD+R DL media, which means in addition to reading Double-Layer DVDs, they can write to a DVD+R DL disc. While single-layer recordable DVDs hold up to 4.7 GB of data, Double-Layer discs have two layers of data, allowing the SuperDrive laser to read and write on both layers, almost doubling the storage to 8.5 GB.
With iDVD (5.0.1 or later) or DVD Studio Pro, you can author discs with over three hours of MPEG-2 video on one DVD+R DL disc. The new SuperDrives can also read and write to DVD-R, DVD+R, DVD-RW, DVD+RW, CD-R, and CD-RW media.
To determine if your SuperDrive is capable of burning Double-Layer DVDs, do the following:
- Open Apple System Profiler (from the Apple menu, choose About This Mac and then click the More Info button).
- Select Disc Burning under Hardware.
- Click on the Burning Device (SuperDrive) name.
- In the DVD-Write section, if you see an item that displays "+R DL," your computer is capable of burning Double-Layer DVDs.
