I want to know that Is " "'rotational equilibrium with constant angular velocity "'" a dynamic rotational equilibrium ?, since " "'Translational equilibrium with constant linear velocity "'" is " Dynamic Equilibrium"

Some other ZBR drives, such as the 800 kilobyte 3.5 " floppy drives in the Apple IIGS and older Macintosh computers, don't change the data rate but rather spin the medium slower when reading or writing outer tracks, thus approximating the performance of constant linear velocity drives.

A motor within the CD player spins the disc to a scanning velocity of 1.2 1.4 m / s ( constant linear velocity ) equivalent to approximately 500 RPM at the inside of the disc, and approximately 200 RPM at the outside edge . ( A disc played from beginning to end slows its rotation rate during playback .)

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.

The spindle motor speed can use one of two types of disk rotation methods : 1 ) constant linear velocity ( CLV ), used mainly in optical storage, varies the rotational speed of the optical disc depending upon the position of the head, and 2 ) constant angular velocity ( CAV ), used in HDDs, standard FDDs, a few optical disc systems, and vinyl audio records, spins the media at one constant speed regardless of where the head is positioned.
