Media 'LT0000002' is overwrite protected

[Hiraman]

I have 5 tapes for 5 days one for each(fixed).When I take backup it gives the above error,but I want to take backup only on that perticular tape because tapes are assigned day wise.

Settings:Overwrite recyclable media contained in targeted media set before overwriting scratch media.

OPP is 1hr and append period is infinite.
