Abstract
A magnetic memory recording component comprising at least a silicon carbide ceramic outer surface. If the silicon carbide ceramic outer surface has a depression in the surface thereof, the maximum depression of the maximum dimension as measured in any direction, e.g. width, depth, length or the like of the depression is less than 0.0001".

A magnetic memory recording component comprising:
- i) a component made of silicon carbide and having an exposed silicon carbide outer surface, a depression in the exposed outer surface of the component having a maximum dimension of 0.0001 inch, and
- ii) the component having no non-stoichiometric silicon and no carbon other than that which is a residual from a process of making silicon carbide ceramic material.
An actuator arm for locating a head relative to tracks on a disk, the actuator arm made of silicon carbide and having an exposed silicon carbide outer surface, a depression in the exposed outer surface of the actuator arm having a maximum dimension of 0.0001 inch, the actuator arm having no non-stoichiometric silicon and no carbon other than that which is residual from a process of making silicon carbide ceramic material.
A magnetic memory coating burnishing head made of silicon carbide and having an exposed silicon carbide outer surface, a depression in the exposed outer surface of the burnishing head having a maximum dimension of 0.0001 inch, the burnishing head having no non-stoichiometric silicon and no carbon other than that which is residual from a process of making silicon carbide ceramic material.
A read/write head made of silicon carbide and having an exposed silicon carbide outer surface, a depression in the exposed outer surface of the read/write head having a maximum dimension of 0.0001 inch, the read/write head having no non-stoichiometric silicon and no carbon other than that which is residual from a process of making silicon carbide ceramic material.
In a magnetic memory recording device having a component for use with a magnetic memory component medium, the improvement comprising said component being made of silicon carbide and having an exposed silicon carbide outer surface wherein a depression on the outer surface has a maximum size of 0.0001 inch and said component has no non-stoichiometric silicon and no carbon other than residual levels resulting from a manufacture silicon carbide ceramic material.
A magnetic clock head made of silicon carbide and having an exposed silicon carbide outer surface, a depression in the exposed outer surface of the clock head having a maximum dimension of 0.0001 inch, the clock head having no non-stoichiometric silicon and no carbon other than that which is residual from a process of making silicon carbide ceramic material.
