摘要： Presented is a data channel with selectable components, such as encoders or decoders. Also, data having different data signal characteristics can be processed through a data channel based on the data signal characteristics. Further, a data channel may have independent encoding path and an independent decoding path. For example, a first data transmission having first data signal characteristics may be processed via a data channel based on a first selected set of components of the data channel and a second data transmission having second data signal characteristics different than the first data signal characteristics may be processed via the data channel using a second selected set of components in the data channel. The first selected set of components may be different than the second selected set of components, but may share one or more common components.

摘要： Values are grouped into a first set of groupings of values. Based on inner codes, the number of groupings in the first set of groupings that have at least one erroneous value is determined. If the number of groupings in the first set of groupings that have an erroneous value is fewer than a maximum number of groupings that can be corrected by outer codes, a seek operation is begun. During the seek operation, the outer codes are used to detect and correct the erroneous values that were produced during the reading of values. In other aspects, a parity section for a data section of a data storage device is dirtied before writing any data to the data section such that if writing to the data section is interrupted, the parity section will indicate that it should not be used to correct data read from the data section.

摘要： An address translation unit is provided for logical to physical address conversion. In particular, apparatus and method are described for receiving a logical cylinder head sector for a logical block address and converting it into a physical cylinder head sector. If a logical block address is received, it is converted to a physical block address and then the physical block address is converted into a physical cylinder head sector. If a logical cylinder head sector is first received, it is converted into a logical block address, and then the conversion takes place just as it would for an initially received logical block address.
