Application No. 10/063,004
modulus of the material for enhanced rigidity relative to
more typical substrate material for optical disks. For
optical recording, however, it is typically desirable to
form a physical format on substrate 12 to facilitate optical
tracking. Therefore, it may be most desirable to form
substrate 12 from a material that can be readily replicated
with a physical format in a mold.
Although Sandstrom indicates that various plastic resins may be
used to form its substrate, it does not specifically mention the
claimed plastic resin.
We observe that Feuerherd refers to JP-A-63-0567832 and
JP-A-63-013722 as disclosing the claimed substrate, i.e., a
substrate made of the claimed plastic resin, which is said to be
useful for magneto-optical computer disks which may be inclusive
of the magneto-optical disks discussed in Sandstrom. See column
1, line 62 to column 3, line 10. They further teach that the
claimed substrate is dimensionally stable and exhibits good
adhesion to the protective layers on top of them and can be
replicated in a mold. Id.
Thus, upon return of this application, the examiner is to
obtain copies of the above-mentioned published Japanese patent
applications and English translations thereof to determine
