This subclass is indented under subclass 127. Subject matter including treatment of the storage medium
surface to produce a modification in a physical characteristic thereof.
(1)
Note. Examples of such treatment include softening
of the storage medium and erasure of a previous track by scraping
or abrading.
Plastic and Nonmetallic Article Shaping or Treating:
Processes,
subclass 36.13 for a process of record disc erasing by shaping, not
combined with mechanical storage thereon.
This subclass is indented under subclass 127. Subject matter wherein the storage medium sensing or modulating
element is mechanically coupled to a sound transmitting or responsive solid
element (e.g., diaphragm), so
as to directly couple the elements.
(1)
Note. The sensing or modulating element is usually
in physical contact with the storage element.
(2)
Note. The term "mechanical" includes
a fluidic coupling.
(3)
Note. Such devices with sound boxes or acoustical
tone arms are classified here, however, the subcombination
limited thereto are classified in the indented subclasses 157-169.
This subclass is indented under subclass 158. Subject matter in which the acoustical coupling structure
includes a plurality of acoustical energy conducting passages through
which such energy may travel simultaneously.
(1)
Note. Such structure may include two acoustical
conduits driven in a mechanical push-pull relationship
by a single stylus.
This subclass is indented under subclass 155. Subject matter limited in extent to a stylus coupled acoustical
resonator, a casing therefor, or a mechanical
linkage used therein.
This subclass is indented under subclass 160. Subject matter having plural styli selectively coupled in
cooperative relationship with the acoustical resonator.
This subclass is indented under subclass 160. Subject matter having a stylus having a tracking motion
limited to an angular displacement about its support from an immovable
casing.
This subclass is indented under subclass 160. Subject matter having acoustical structure for amplifying, muffling
or filtering the incident or reproduce sound.
This subclass is indented under subclass 160. Subject matter including structure to cause or respond to
stylus vibrations in two planes, one being normal and the
other parallel to the record medium surface.
(1)
Note. Such structure in a reproducer may be unitary
or alternative.
This subclass is indented under subclass 160. Subject matter wherein the sound box causes or is responsive
to stylus vibration in a plane normal to the surface of the storage
medium.
This subclass is indented under subclass 165. Subject matter having structure to increase the amplitude
of the mechanical vibrations of the elements coupling the stylus
and acoustical resonator.
(1)
Note. Such structure is often a frictional linkage
to an auxiliary vibrating structure.
This subclass is indented under subclass 165. Subject matter having a stylus supporting lever with counterbalancing
weight structure to minimize or eliminate the weight applied by
the stylus.
This subclass is indented under subclass 160. Subject matter wherein the sound box causes or is responsive
to stylus vibration in a plane tangent, or parallel the
surface of the storage medium.
This subclass is indented under subclass 127. Subject matter limited in extent to a support or a protecting
device for the storage medium engaging element with or without such
element.
This subclass is indented under subclass 170. Subject matter having structure to select one of a plurality
of styli for engagement with the storage medium.
