Constant angular acceleration (CAA) is a variant of CLV that is used on the LaserDisc format. The initial specification of CLV (as it applies to laserDisc) results in several playback artifacts to be present in the audio/video portion as well as compatibility problems with LaserDisc players as produced by different manufacturers.
The space-consuming analog video signal of a LaserDisc limited playback duration to 30/36 minutes (CAV NTSC/PAL) or 60/64 minutes (CLV NTSC/PAL) per side, because of the hardware manufacturer's refusal to reduce line count and bandwidth for increased playtime, (as was done in VHS; VHS tapes had a 3 MHz video bandwidth, while LaserDisc preserves ...
The LV-ROM is a specialized variation of the CAV Laserdisc. LV-ROM is an initialism for "LaserVision Read-Only Memory". Like Laserdisc, LV-ROM discs store analog audio and video by encoding it in pulse-width modulation. However, LV-ROM also stores computer files via the Advanced Disc Filing System, which is the file system used by Acorn Computers.
In contrast, in CLV mode, the spindle motor speed varies so that the medium passes by the head at the same speed regardless of where on the disk the head is positioned. If the disk is recorded at the same areal density throughout, then when read or written in CAV mode, the data rate is higher for the outer tracks than for the inner tracks ...
Other factors that affect data storage density include: the existence of multiple layers of data on the disc, the method of rotation (Constant linear velocity (CLV), Constant angular velocity (CAV), or zoned-CAV), the composition of lands and pits, and how much margin is unused is at the center and the edge of the disc. Types of Optical Discs:
This feature allows for observing the writing speeds and patterns (e.g. constant angular velocity, constant linear velocity and P-CAV and Z-CLV variants) with different writing speed settings and testing the highest capacity of an individual disc that would be achievable using overburning. [8]

The Z-CLV recording pattern is easily visible after burning a DVD-R. The first laser disc, demonstrated in 1972, was the Laservision 12-inch video disc. The video signal was stored as an analog format like a video cassette.
