Abstract
Methods and arrangements are provided to significantly reduce the processing burden in a data storage device and streamline the transfer of frames of data from the storage device to an external device, by taking into account certain known or otherwise determinable characteristics about the data recorded on the storage medium and selectively applying tag data to each frame of data. The tag data is then used to determine the disposition of each frame of data, and what actions if any are required to process the frame of data within the storage device. Since this "tagging", which can be logical or physical, can occur at an early stage in the circuitry of the storage device, the amount of subsequent processing is significantly reduced. Consequently, the latency associated with the storage device is also reduced. The various embodiments of the present invention can be used for a variety of data storage devices including, but not limited to, optical disc drives, magnetic drives and tapes, and similar data storage devices.
