drives as well as for consistency in recording levels on the
hard disk cartridges. An embedded servo method is used for
magneto-resistive hard disk recording.1
Independent claim 1 is as follows:
1. A rotating disk drive for the magnetic storage of
computer data, comprising:
a grounded actuator arm with an inductive head for
writing and a magneto-resistive (MR) read head for reading a
plurality of data tracks with embedded servo features on a
surface of a rotating magnetic rigid disk within a removable
cartridge;
grounding means for connecting said rotating magnetic
rigid disk to a disk drive ground and the actuator to provide
electrostatic discharge (ESD) protection to said MR head,
wherein the voltage potential between said MR head and said
rotating magnetic rigid disk is limited to two to three volts;
and
cartridge receiving means proximate to the magneto-
resistive read head for accepting and ejecting said removable
cartridge.
No prior art is relied upon by the Examiner in the
rejection of claims under appeal.
Claim 2 is rejected under 35 U.S.C.§ 112, second
paragraph. Claims 1-4 and 7-8 are rejected under 35 U.S.C.§
112, first paragraph. Appellant has indicated that claims 1-4
and 7-8 stand or fall together.
