Abstract: PURPOSE:To prevent the adhesion of dust and dirt to a magnetic tape so as to prevent the occurrence of dropout by providing a tape protective member which protects the magnetic tape from the rear side and constituting the tape protective member so that the member makes opening operations when the magnetic tape is taken out. CONSTITUTION:When a tape cassette A is not used, the rear surface of a magnetic tape 3 is covered by means of tape pads 9a and 9b between tape guides 8a and 8b. The tape pads 9a and 9b have an elastic property and, when the tape cassette A is loaded on a recording and reproducing device, the front lid of the cassette A is opened and a tape loading member on the recording and reproducing device side enters the cassette. Then the magnetic tape 3 is drawn out and put on a magnetic head and the tape pads 9a and 9b are simultaneously opened by means of the tape loading member. Therefore,the occurrence of dropout can be suppressed, since dust and dirt hardly adhere to the magnetic tape 3, and the recording and reproducing characteristics of the magnetic tape can be improved.
