Data storage device and a method for providing a synchronization signal for at least one of a read operation or a write operation carried out by means of a head in a data storage device

摘要

According to embodiments of the present invention, a method for providing a synchronization signal for at least one of a read operation or a write operation carried out by means of a head in a data storage device is provided. The method includes obtaining a readback servo signal from a storage medium of the data storage device by means of the head, the readback servo signal having at least one frequency associated with a servo track of the storage medium, frequency mixing the readback servo signal with a local signal having a local frequency to provide a frequency mixed signal, and filtering the frequency mixed signal to provide the synchronization signal for at least one of the read operation or the write operation. According to further embodiments of the present invention, a data storage device is also provided.

1. A method for providing a synchronization signal for at least one of a read operation or a write operation carried out by means of a head in a data storage device, the method comprising:
obtaining a readback servo signal from a storage medium of the data storage device by means of the head, the readback servo signal having at least one frequency associated with a servo track of the storage medium; frequency mixing the readback servo signal with a local signal having a local frequency to provide a frequency mixed signal; and filtering the frequency mixed signal to provide the synchronization signal for at least one of the read operation or the write operation, wherein filtering the frequency mixed signal comprises bandpass filtering or low pass filtering the frequency mixed signal for passing a component of the frequency mixed signal having a down-converted frequency to provide the synchronization signal.
