| The client is able to open seekable streams on the server, either in read-only or read-write access mode. |
| This moves the tape forward with the read-write head positioned at the end of the following record. |
| At this point, she has shifted her checked-out copy from the read-only mirror over to a read-write archive hosted on her laptop. |
| The read-write check flag or the end of record flag is then interrogated to see that the tape is actually at the end of record. |
| When a tape is stretched, it may reduce head-to-tape contact, increasing read-write errors and dramatically reducing data throughput. |
| Armed with read-write data, library managers can fine tune performance and ensure that all disks are operating at appropriate levels. |
