Abstract
For performing a retry in a data storage device, a spin jitter value corresponding to a desired sector of a disc is determined. A read timing is adjusted according to the spin jitter value of the desired sector. A retry of a data read is performed for the desired sector with the adjusted read timing. Thus, the present invention accounts for eccentricity of the disc as indicated by the spin jitter value during retry of the data read operation.
