摘要： A length of a separator to be skipped on the storage disk is compared with a threshold. The threshold is associated with a maximum value for which a timing loop is able to be paused without causing the timing loop to have inaccurate timing. If the length is greater than the threshold, a first split sector format is assigned to the split sector and that information is recorded. In such cases, a first portion and a second portion both include synchronization information. If the length is less than the threshold, a second split sector format is assigned to the split sector and that information is recorded. In such cases, the first portion includes synchronization information and the second portion of the split sector excludes synchronization information.

摘要： A technique for blind channel estimation is disclosed herein. A read value that is read from a multi-level storage device is received, as are a set of bins having bin ranges and (for each of the bins in the set) a corresponding portion of read values which fall into that particular bin. One or more of the bin ranges is adjusted such that the received portions of read values remain substantially the same after adjustment and after assignment of the read value to one of the set of bins after adjustment.

摘要： An offset compensation scheme using a digital-to-analog converter (DAC) is disclosed. In some embodiments, a DAC is coupled to a circuit having an undesired current or voltage offset and is configured to at least in part compensate for the undesired current or voltage offset. For example, in some embodiments, the DAC injects current or voltage into the circuit that shifts a current or voltage of the circuit by an amount equal or similar in magnitude but opposite in polarity to a shift in the current or voltage of the circuit caused by the undesired current or voltage offset.
