Field :
Storage structure CAV

Atoneof the roll control systems in the storage unit which utilizes the media of the disk condition of CD and the like, the system which maintains rpm uniformly. Circumference because about outside it becomes long, the speed where the head traces the record aspect (linear velocity) about inside becomes slow, about outside fast, also reading and writing speed of the data changes attendant upon this.

As for the program and the graphics data as for the necessity for the speed which reads out the data to be fixed it is not, it readsthe data of the various places discontinuously in addition different from music CD and the like, because(randomaccess) there is many a thing, as for rpm fixed one is convenient. Because of thisCD-ROMdrive and the like has adopted CAV.

On the one hand, changing rpm, as for the system which maintains linear velocity uniformly and controls CLV(Constant Linear Velocity: Linear velocity uniformity) with it is called.Because as formusic CD and the like it is necessary for read-out speed of the data to be fixed,the CD player et. al.has becomeCLV.
