Disc Image Format A disc image is a single file, saved on you hard disk, that contains ALL the data and formatting information needed to create the CD. With Disc Image format you can write a previously-saved file to a CD, using disc images created by Toast. When to Choose Disc Image Format • For recording selected data youÕve saved as a disc image in Toast. • To record a disc image to CD when you donÕt know what was used to create it. • To record an ISO image with Rockridge extensions you created with a UNIX utility (such as "mkisofs"). • 31. To record multiple copies of a CD. Preserving Dates on a Disc Image Before you get ready to record, decide whether you want to preserve the creation and modified dates associated with the files contained in the disc image. If the dates are important, lock the disc image before you mount it. Otherwise, the disc image assumes the recording date as the modification date. 1 Select the disc image icon. 2 Choose Get Info from the File menu, and then choose General Information from the submenu. 3 In the Info window that appears, click the Locked check box to select it. When you finish, the disc image icon includes a small padlock. Recording a CD in Disc Image Format Before you can use Disc Image format, you must create a valid disc image on your Macintosh. As an alternative to the drag-and-drop method, you can click the Select button and use the Open dialog box to locate the disc image you want to record. To see the contents of the disc image and make sure everything is set up the way you want, click Mount. The disc image is mounted on your desktop. You can double-click it to open it and inspect its contents. To determine whether the CD is still recordable, choose Disc Info from the Recorder menu. 1 Click Other in the Toast window and hold down the mouse button 2 From the pop-up menu that appears, chose Disc Image 3 Drag the disc image you want to the Toast window 4 When you are ready, insert a blank CD into your CD-Recorder. 5 Click the Record button. 6 In the Record dialog box, verify the speed is correct and select the option you want: • If you want to leave open the possibility of recording additional tracks or data at another time, click Write Session. (If the resulting CD would be nearly full, this option is disabled.) • To close the CD so that no further data can be added later, click Write Disc. 7 Finish the recording process appropriately for the recording format you used: • For a data CD, when all the data is written, Toast pauses briefly, then automatically verifies the data. (You can prevent verification by clicking Eject during the pause.) When you see the message, "Verification completed successfully," click Eject. • For a music CD, when you see the message, "Your disc is ready," click Eject.   Upgrading to Toast 5 Titanium
