Living up to its promise at last month’s Macworld Expo in San Francisco, Apple has rolled out iTunes 1.1, improving stability, adding keyboard controls, and providing support for burning audio CDs using more than two dozen third-party CD-RW drives. iTunes enables users to burn audio CDs based on playlists of MP3 files (or other audio formats supported by iTunes); these audio CDs hold only up to the standard 74 minutes of audio, but they can be used in any standard audio CD player. Although it’s possible to store many hours of music in MP3 format on the 650 MB available on a data CD and play those in computers or specialized CD-MP3 players, iTunes can’t create data CDs. For that you’ll need to use Apple’s Disc Burner (for recent Macs with Apple’s internal CD-RW) or third-party software like Roxio’s Toast or CharisMac’s Discribe (for all other third party CD-R and CD-RW drives). iTunes 1.1 is available for free from Apple as a 3.6 MB download; it requires at least Mac OS 9.0.4 (Mac OS 9.1 for burning CDs).
