초록 ▼

A rotary magnetic record disk assembly comprising a magnetic disk which is rotatably disposed within a containing jacket of material of high electrically insulating characteristics. An electrically conductive layer is disposed on the inside surface of the jacket for draining away electrostatic charg

대표청구항 ▼

A magnetic record assembly including: a magnetic disk of highly electrically insulating, flat, uniform thickness sheet material, a jacket of highly electrically insulating material enclosing said disk and having a central opening through it by means of which the disk may be rotatably driven within the jacket and having a slot therein for receiving a magnetic transducer to have a data transferring relationship with the disk and having flat internal faces adjacent to and extending along the faces of said disk, a layer of a porous low friction dusting fabric within said jacket and in wiping contact with the faces of said disk as the disk rotates within the jacket, and a uniform thickness flat thin layer of electrically conducting non-porous material within said jacket and in contact with and between said flat internal jacket faces and said layer of dusting fabric for draining static electricity from the jacket.
