blocked records
blocked records
(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.
