24x max cd-rom

CD-ROM drives that are over 16x have max written next to it. When max is written next to the speed or on the drive, it indicates that the CD-ROM uses constant angular velocity, to access its data. Originally, CD-ROM drives utilized CLV (constant linear velocity), which accessed data slower or faster by changing the speed of the motor to transfer the data at a steady flow.

With CAV, the CD rotates at a constant speed, which means a 32x speed CD-ROM, for example, can access the data 32x on the outside layer. However, when approaching the middle of the CD-ROM drive, the access speed can decrease close to 20x.
