In an approach for writing data on a tape using a file system, a processor receives a first write request of a first file. A processor obtains data of the first file. A processor writes the data of the first file on a tape. A processor receives a second write request of a second file prior to completion of writing the data of the first file on the tape. A processor adds information about the second file to a first list, wherein the first list includes files waiting to write. Subsequent to writing the data of the first file on the tape, a processor obtains data of the second file based on the first list. A processor writes the data of the second file after the first file on the tape.

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.

A tape apparatus includes a tape drive and a processor. The tape drive is configured to perform data reading and data writing on a magnetic tape in which a plurality of tracks are formed. The processor is configured to control the tape drive to perform data reading and data writing on the plurality of tracks in a first segment among a plurality of segments obtained by dividing the magnetic tape in a running direction. The processor is configured to reserve a first track of the plurality of tracks as a copy target upon determining that an abnormality occurs in the first segment on the first track. The processor is configured to instruct the tape drive to copy data recorded in the first segment on the first track to a second segment on the first track at a predetermined timing. The second segment is adjacent to the first segment.

A two part process is used for modifying records to be written and retrieved from tape devices. A record is appended with a cyclic redundancy check and a string of zeros. Submitting the entire record to tape drives which are logical block protection enabled will result in no change. For drives that are not LBP enabled, the string of zeros at the end of the record is removed. In addition to determining whether a drive is LBP compliant, a determination may be made as to whether a drive is a linear tape open drive from a particular manufacturer. Linear tape open drives may behave similarly as drives which may not be enabled with logical block protection.
