A magnetic recording and reproducing apparatus which enables selective loading of a plurality of kinds of magnetic tape cassettes (1, 3) of different sizes, including a slider (6) which receives a large magnetic tape cassette (3) horizontally from an insertion position of the large magnetic tape cassette (3) so as to displace the large magnetic tape cassette (3) horizontally and then, lowers the large magnetic tape cassette (3) vertically and an adapter chassis (14) into which a small magnetic tape cassette (1) is fitted so as to be locked thereto. Upon detection of fitting of the small magnetic tape cassette (1) into the adapter chassis (14), a magnetic tape (1a) is drawn from the small magnetic tape cassette (1) by first and second tape drawing arms (22, 23) mounted on the adapter chassis (14) and upon detection of a state in which the magnetic tape (1a) has been drawn from the small magnetic tape cassette (1) and the slider (6) has been displaced to a position (6P) for performing recording and reproduction, the adapter chassis (14) is loaded onto the slider (6) located at the position (6P) for performing recording and reproduction. |
