A rigid disk substrate for a magnetic recording disk is formed of a ceramic-metal matrix composite.
A method for planarizing or polishing a memory or rigid disk is provided.
The shaft holds an upper rigid disk that is connected to a motor.
The grooves (9) of the rigid disk (7) form together with the flexible disk (6) conduits for the product to be ejected and are so orientated that they form a tangent with the circumference of the axial conduit (10) of the rigid disk (7).
The inclined shaft (17) which carries the rigid disk (18) is rotated by a motor (22).
An insulating and waterproof intermediate layer (3) is disposed between the conductive disc and the rigid disc.
The cover is composed by a disc (2) made of an electrically conductive material, a rigid disc (1) covering the face which obturates the housing.
Disclosed herein is a carrier for a rigid data storage disk (6), e.g. an optical, magnetic or magneto-optic disk, for facilitating the transport of such disk within a disk library or the like.
A stiff disc (66) is disposed between the foam element and bag and includes a central through hole.
An apparatus for texturing the front and back surfaces of a rigid-disk substrate (30) used in magnetic recording systems is disclosed.
The rigid obturating disc has an opening (8) in which projects the traversing element (9, 13).
The intermediate layer (3) may be composed of an organic or inorganic material.
The rigid disc (1) may be composed of a conductive or non conductive material.
The object of the invention is a cutting device to be used with portable trimmers, made by a rigid disc (1) where several centrifugal cutting blades (2) are conveniently fixed.
One additional embodiment includes a cantilever hinge and rigid polymer disc to convert one diaphragm into a linearly deflecting diaphragm.
A wave generator (4) of a wave gear device (1) is equipped with a rigid cam plate (5) and a wave bearing (7).
