  • Article

The WRITE_ROTATION enumeration specifies whether a CD-ROM drive uses constant linear velocity (CLV) rotation or constant angular velocity (CAV) rotation when it writes to a CD.

Syntax

typedef enum _WRITE_ROTATION {
  CdromDefaultRotation,
  CdromCAVRotation
} WRITE_ROTATION, *PWRITE_ROTATION;

Constants

 
CdromDefaultRotation
The CD-ROM drive uses the (default) constant linear velocity (CLV) method when it writes to a CD.
CdromCAVRotation
The CD-ROM drive uses the (default) constant angular velocity (CAV) method when it writes to a CD.

Requirements
