advantageously to end the optical storage medium or why these
properties would be desirable.
Upon our review of Utsumi, we find that Utsumi is related to
an electrostatic information-recording medium which can
electrostatically record information by an exposure process with
the application of voltage or other processes and reproduce the
information at any desired time. See column 1, lines 14 through
22, of Utsumi. Utsumi teaches by referencing figures 1 and 2 an
electrostatic information-recording medium having a charge-
retaining layer 11, a resin layer having a low glass transition
temperature 11a a heat-resistant, non-photoconductive insulating
layer 11b, an electrode 13 and a support 15. See column 6, lines
55 through 67. Utsumi teaches that there are various materials
that are suitable for making the resin layer. Among many of
these materials, Utsumi teaches that the resin layer could be
made of amorphous selenium. See column 9, lines 6 through 31 of
Utsumi. Utsumi teaches that the resin layer is made of amorphous
selenium as well as other materials for their properties of
providing photoconductive or electrically conductive material in
order to stabilize charges carried thereby. Id.
