Abstract
A tape cleaner for a magnetic recording and reproducing apparatus includes a plurality of blades disposed so that their tip portions are simultaneously in contact with a magnetic tape in the transportation path of the magnetic tape to remove dust and magnetic powder attached to the magnetic tape, whereby dropout can be prevented and a highly demanding error rate can be satisfied.
Claims11
A tape cleaner for a magnetic recording and reproducing apparatus disposed in a transportation path of a magnetic recording medium comprising:
- a holder;
- a foregoing blade mounted on said holder and having a slant surface and a bottom surface forming a tip at one corner thereof, said foregoing blade having a concave portion formed therein;
- and
- a following blade engaged in said concave portion of said foregoing blade and mounted on said holder by a fixing member arranged between an upper portion of said following blade and said holder, said following blade being at a position after said foregoing blade when said magnetic recording medium travels in a forward direction and having a slant surface and a bottom surface forming a tip at one corner of said following blade, such that said tip of said foregoing blade and said tip of said following blade are simultaneously in contact with a surface of said magnetic recording medium to clean said magnetic recording medium,
- wherein said tip of said foregoing blade and said tip of said following blade are oriented in a same direction opposite the forward travelling direction of said magnetic recording medium and an angle of said slant surface of said following blade relative to said magnetic recording medium is larger than an angle of a slant surface of said foregoing blade relative to said magnetic recording medium.
