Prediction of track misregistration due to disk flutter in hard disk drive

Disk runout consists of repeatable runout (RRO) and nonrepeatable runout (NRRO). NRRO is the main cause of track misregistration that prevents a high track density, whereas tracking servo control can compensate for most of RRO. An increase in the disk rotation speed increases the amplitude of disk f...
