The recording apparatus comprises a first writing prohibition detection switch to be inserted to an discrimination hole formed on both cassettes and receded in accordance with an open/close state of a writing prohibition discrimination hole provided on the current-used cassette, a second writing prohibition detection switch to be receded in accordance with an open/close state of a writing prohibition discrimination hole formed in the new tape cassette, and a cassette type detection switch to be inserted to an discrimination hole formed in the new tape cassette and receded by a side surface of the current-used cassette. A control circuit discriminates a new tape cassette from the current-used tape cassette.
