Data Protection
Write-Protection of the Data Cartridge While Inside the Drive

does not take effect until the write operation is completed.
S If you move the Write-Protect switch from the write-protected position
(on the left) to the write-enabled position (to the right), the tape becomes
write-enabled after several seconds.
S If you move the Write-Protect switch from the write-enabled position
(on the right) to the write-protected position (to the left), the tape becomes
write-protected after several seconds.
