Abstract
Provided are a computer program product, device, system, and method for write data management. In one embodiment, a write management controller calculates an order for writing data and parity blocks of write data code words on tape media in a variable interleaved fashion which ensures a minimum physical longitudinal separation along the length of tape between data and parity blocks of the same code word. The calculated write order information may be provided back to a host or other data source so that the write data is eventually transmitted to the tape drive for writing on tape media in accordance with the calculated write order. In this manner, a minimum physical longitudinal separation along the length of tape between data and parity blocks of the same code word may be achieved to increase the reliability of the data storage.
