Type II tapes are harder to erase and record to that Type I. They require more erasing and biasing power. Type IV tapes even more so.

A tape machine capable of recording to Type II or IV tapes will usually state as much somewhere on the front panel. If it doesn't, it probably cant.

A line level signal is too high for a mic level input. It will distort, and possibly damage the recorder's electronics.
