OPTICAL DISK DRIVE MODIFIED FOR SPEED AND ORIENTATION TRACKING

摘要

An optical disk drive (100) includes a spindle motor (706) to turn an optical disk (100) and an OPU (710) configured to apply an image (118) to a coating within a label region (106) of the optical disk (100). An encoder (406) is configured for tracking disk speed features (112) on the optical disk (100) in a region distinct from the label region (106) defined on the disk (100). By tracking the disk speed features (112), the encoder (406) obtains disk speed data for use in applying the image to the label region (106).
