Title: System and method for reading unidirectionally recorded data bidirectionally

Abstract: A system and method for allowing uni-directional data to be read in the reverse direction as well as the forward direction uses a data buffer to reverse the order of data read from storage media. Data are read from the storage media in the reverse direction and stored in a data buffer. Pointers are set up to track record boundaries of the data storedin the data buffer. The data are read from the data buffer in the opposite direction from which they are stored and sent to a host in the forward direction. Cyclic redundancy checks can be performed as data are read from the storage media in the reverse direction and read from the data buffer in the forward direction.
