Abstract
A disk cartridge and a disk recording and/or reproduction apparatus including a protrusion group which is made up of a plurality of protrusions and formed within a case housing a disk or within a housing in which a disk is loaded. Accordingly, the protrusions induce the flow of air generated during the rotation of the disk to serve as a force generated by variations in flow velocity and pressure. Therefore, foreign materials can be effectively removed from the surface of the disk using the flow of air without a separate cleaning apparatus.
Claims14
A disk cartridge or housing comprising:
- a case housing an information recording and/or reproduction disk and a shutter which is installed on the case and secretively opened and closed to accomplish an access to the disk by a recording and/or reproduction apparatus;
- and
- a protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed on an inner wall of at least one of the case and the shutter, and extending linertly radially in paralled from a rotational axis of the disk.
A disk cartridge or housing comprising:
- a case housing an information recording and/or reproduction disk and a shutter which is installed on the case and secretively opened and closed to accomplish an access to the disk by a recording and/or reproduction apparatus;
- and
- a protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed on an inner wall of at least one of the case and the shutter,
- wherein the protrusion group includes at least two protrusion groups each disposed at an equiangular interval in a direction of rotation of the disk.
A disk cartridge or housing comprising:
- a case housing an information recording and/or reproduction disk and a shutter which is installed on the case and secretively opened and closed to accomplish an access to the disk by a recording and/or reproduction apparatus;
- and
- a protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed on an inner wall of at least one of the case and the shutter,
- wherein the protrusion group includes protrusion groups arranged in a stepped manner in a radial direction of the disk.
A disk cartridge having an information recording and/or reproducing disk comprising:
- a case enclosing the disk;
- and
- at least one protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed within said case, and being positioned in parallel linertly in the radial direction of the disk.
A disk cartridge having an information recording and/or reproducing disk comprising:
- a case enclosing the disk;
- and
- at least one protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk, the protrusion group being formed within said case, and being positioned in parallel linertly in the radial direction of the disk, wherein the pugnacity of protrusions are adjacent to each other such that they form a sine curve shape configuration.
A disk cartridge having an information recording and/or reproducing disk comprising:
- a case enclosing the disk;
- and
- at least one protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed within said case,
- wherein the protrusion group is plural in number and includes protrusion groups arranged in a radial direction of the disk in a stepped manner.
A disk recording/reproducing apparatus for recording information on or reproducing information from a disk while rotating the disk, comprising:
- a housing;
- and
- a protrusion group having a pugnacity of protrusions each protruding therefrom and toward the disk so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the disk on the surface of the disk, the protrusion group being formed within the housing, and being positioned in parallel linertly in the radial direction of the disk.
A disk cartridge comprising:
- a case to house an information recording and/or reproduction medium;
- a shutter, which is installed on the case, to be secretively opened and closed so as to provide access for a recording and/or reproduction apparatus to the medium;
- and
- a pugnacity of protrusions, attached to at least one of the case and/or the shutter, to protrude toward the medium so as to generate a sinusoidal air pressure profile having an initial increasing and then decreasing amplitude in the outward radial direction of the medium on the surface of the medium.
