Appeal No. 97-2035
Application 08/161,234
The invention is directed to a magnetic disk storage
system having increased reliability due to a reduction of
electrostatic charge accumulation on the slider head assembly
(independent claims 1 and 15), and a method for reducing
debris accumulation in a magnetic disk storage system
(independent claim 9). Key to each of these independent
claims is an electrically conducting path connecting the
conductive coating on the slider head assembly with the
electrically conductive storage disk. Representative claims 1
and 9 are reproduced below:
1. A magnetic disk storage system with
increased reliability by the reduction of
electrostatic charge accumulation on the
magnetic disk storage system’s slider head
assembly due to triboelectric effects, the disk
storage system comprising:
a) an electrically conductive storage
disk with a magnetic recording surface that is
in contact with a slider/head assembly load-
bearing conductive surface when at rest, the
disk rotating and in contact with or in close
proximity to a slider/head assembly magnetic
transducer when writing data to or reading data
from the disk;
b) the slider/head assembly including:
i) a slider with a load-bearing
surface that is in contact with the magnetic
