Abstract
In a recording and/or reproducing apparatus of the kind having a recording and/or reproducing head arranged to be shiftable in the radial direction of a flexible disc, which is used as a record bearing medium, and a disc stabilizing member which is provided with a recessed part formed along the path of the movement of the head. The recessed part is formed to have a wider opening width at its portion located closest to the center of the disc than at its portion located closest to the outer periphery of the disc.
Claims15
A record and/or reproducing apparatus using a disc-shaped flexible record-bearing medium, comprising:
- (a) rotation means for rotating the medium;
- (b) a recording and/or reproducing head arranged to confront a recording surface of the medium and movable in a radial direction of the medium;
- and
- (c) a stabilizing member arranged to confront another surface of the medium thereby sandwiching the medium between the stabilizing member and said head, said stabilizing member having a recessed portion formed therein extending along a path of movement of said head, a width of said recessed portion, in the radial direction of said medium, being larger at a central portion of the medium than a peripheral portion of the medium.
A magnetic recording and/or reproducing apparatus using a flexible magnetic disc having a center core, comprising:
- (a) a spindle engageable with the center core of the disc for rotating the disc;
- (b) a magnetic head arranged to confront a recording surface of the disc and movable in a radial direction of the disc;
- and
- (c) a plate-shaped member arranged to sandwich the disc between the plate-shaped member and said head, said plate-shaped member having a surface thereof confronting another surface of the disc and having a recessed portion formed in said surface of the plate-shaped member extending along a path of movement of said head to avoid contact of the plate-shaped member with the head, a width of said recessed portion, in the radial direction of said medium, being larger at a central portion of the medium than at a peripheral portion of the medium.
A recording or reproducing apparatus having a recording or reproducing head which is shiftable in a radial direction of a flexible disc, and a stabilizing member, located opposite to said head across said disc, having formed therein a recessed part extending along a shifting path of said head, characterized in that said recessed part has a wider opening width, in the radial direction of said medium, at a central portion of said disc than at a peripheral portion of said disc.
A recording or reproducing apparatus having a recording/reproducing head and a stabilizing member for stabilizing a rotating motion of a flexible record-bearing disc, wherein said stabilizing member and said head are on opposing sides of said disc, said member comprises:
- a recessed part which is provided approximately in the middle part of said member for the purpose of avoiding contact with a recording or reproducing head, and is arranged to have a wider opening width, in the radial direction of said disc, at a central portion of said disc than at a peripheral portion of said disc.
A recording or reproducing apparatus haveing a recording/reproducing head and a stabilizing member for stabilizing a rotating motion of a flexible record-bearing disc, said head and said member being on opposing sides of said disc, wherein said stabilizing member is of a non-contact type with said disc, and comprises:
- a recessed part which is provided in said member for avoiding contact with said recording or reproducing head, wherein said recessed part has a variable shape in a radial direction of said disc, a width of said recessed part being wider at a central portion of said disc than a peripheral portion of said disc.
