  • Patent number: 11823709
    Abstract: In an approach to improving write performance by enabling host data transfer immediately after a reposition command, responsive to receiving on a tape drive a reposition command from a host, a ready response is returned to the host. Write data from the host is accumulated in a write buffer, where the write data is accumulated in the write buffer while simultaneously moving a tape media in the tape drive to a target location. The write data from the write buffer is written to the tape media immediately after the target location is reached on the tape drive.
