Abstract
A method of forming a batch of uniformly shaped glass sheet objects is disclosed. A stack of glass sheets is placed in a frame and submerged in a coolant. A hole is drilled through the stack. The cores of the hole and any debris from the drilling process are swept away in the coolant and pumped through a filter. A pin is inserted into the hole and attached to the base. A head on the pin, or a washer, fixes the stack of glass to the base at the hole. An outer profile is then cut in the glass stack around the hole while the formed objects are held to a base of the frame by the pin. Again, any debris is swept away in the coolant. The uniformly shaped objects are removed from the frame and separated. The glass sheet objects are preferably usable as a substrate for a magnetic or magneto-optical (MO) data/information storage retrieval medium.
