Claims
- 1. A retaining mechanism for retaining a flexible magnetic sheet in a position for magnetic communication with a magnetic head, comprising:
- a lower retaining member having a first convex portion with a slot therein and positioned with respect to said magnetic head and said magnetic sheet so that said magnetic head communicates with the underside of said magnetic sheet through said slot, said lower retaining member having a second convex portion displaced from said first convex portion to form a recess between said convex portions; and
- an upper retaining member of convex shape which penetrates said recess in said lower member, and which is positioned on the opposite side of said magnetic sheet from said lower retaining member to thereby press said flexible magnetic recording sheet into said recess.
- 2. A retaining mechanism as recited in claim 1, wherein said lower retaining member comprises:
- a second slot in said second convex portion positioned with respect to a second magnetic head and said magnetic sheet so that said second magnetic head communicates with the underside of said magnetic sheet thru said second slot.
- 3. A retaining mechanism as recited in claim 1, wherein said magnetic sheet is a magnetic disc rotatable about an axis and said lower retaining member remains stationary with respect to said axis, and wherein said slot is elongated to thereby permit said magnetic head to move radially relative to said flexible magnetic recording disc.
- 4. A retaining mechanism as recited in claim 1, wherein said magnetic sheet is a magnetic disc and said lower retaining member moves radially relative to said flexible magnetic recording disc.
