How to get magnetic tape from Panasonic md9000 camera

There is a switch button on the cassette. When this switch is toggled, the tape cassette will automatically open. Generally speaking, this is how the tape is taken out.

Take out the tape from the broken Panasonic camera: it can only be disassembled. If the machine is scrapped and doesn't want it, you can dismantle it yourself. If you still want the machine, you need to go to the digital maintenance center and ask the master to disassemble it.
