The new iMac model has a 24X-speed internal CD-ROM drive. The CD-ROM drive supports the worldwide standards and specifications for CD-ROM and CD-digital audio discs described in the Sony/Philips Yellow Book and Red Book. The drive can read CD-ROM, CD-ROM XA, CD-I, and PhotoCD discs as well as play standard audio discs.
The CD-ROM drive uses slot loading of the disc. The drive features a mechanism that supports 4X, 8X, 12X, and 24X data transfer rates and a data buffer that further enhances performance.
Digital audio signals from the CD-ROM drive can be played through the sound outputs under the control of the Sound Manager.
The CD-ROM drive is an ATAPI drive and is connected as device 1 (slave) in an ATA Device 0/1 configuration.
