Setting The Write-Protect Tab On 1/4-Inch Tape Cartridges - IBM 7013 J Series Operator's Manual

Setting the Write-Protect Tab on 1/4-Inch Tape Cartridges

Setting the write-protect tab on a tape cartridge is necessary so that information is not
accidentally lost. When the write-protect tab of a tape cartridge is set (pointing to SAFE),
information can be read from the tape, but cannot be written to it.
The write-protect tab positions for a typical cartridge are shown in the following illustration.
Use a small screwdriver to turn the arrow to the desired position. The arrow must be
pointing in one of the two directions shown in the illustration.
Re-tensioning
The tape drive works best when it is operated as a streaming tape. Before the first use of a
1/4-Inch cartridge you must retension the tape.
If the tape drive is on when a tape cartridge is inserted, the drive immediately retensions the
tape. Operating system commands can be used to change this default setting. Refer to the
operating system commands manual for your system for more information.
