<storage> Several records written as a contiguous block on magnetic tape so that they may be accessed in a single I/O operation. Blocking increases the amount of data that may be stored on a tape because there are fewer inter-block gaps. It requires that the tape drive or processor have a sufficiently large buffer to store the whole block.
