Claims
- 1. An apparatus for supporting an optical system in an optical information recording and/or reproducing apparatus comprising:
- an optical system holding member for holding the optical system such that the optical system is opposed to an optical record medium;
- a stationary member provided on a carriage which is movable in a given direction with respect to the optical record medium;
- a supporting means for supporting said optical system holding member movably in at least one direction with respect to said stationary member and including at least two independent supporting members having a uniform length and spaced apart at a predetermined height therebetween, said two supporting members having ends offset in a radial direction with respect to the optical recording medium, and said two supporting members having first ends secured to said optical system holding member and second ends secured to said stationary member; and
- a damping member provided between said two supporting members, said damping member comprising a fluidizable damping material injected into a space formed between said two supporting members and retained in position between said two supporting members by surface tension.
- 2. An apparatus according to claim 1, wherein at least one of said two supporting members has formed therein an opening through which said fluidizable damping material has been injected into the space formed between the two supporting members.
- 3. An apparatus according to claim 1, wherein said damping member is formed by curing the injected fluidizable damping material.
- 4. An apparatus according to claim 1, wherein said two supporting members are arranged in parallel with each other with a small distance therebetween corresponding to said predetermined height.
- 5. An apparatus according to claim 1, wherein said surface tension is directly between and in sole contact with said two supporting members.
- 6. An apparatus for supporting an optical system in an optical information recording and/or reproducing apparatus comprising:
- an optical system holding member for holding the optical system such that the optical system is opposed to an optical record medium;
- a stationary member provided on a carriage which is movable in a given direction with respect to the optical record medium;
- a supporting means including at least two independent supporting members having a uniform length and spaced apart at a predetermined height therebetween, said two supporting members having first ends and second ends offset in a radial direction with respect to the optical recording medium, and said two supporting members having said first ends connected to said optical system holding member and said second ends connected to said stationary member, said supporting means supporting said optical system holding member movably in at least one direction with respect to said stationary member; and
- a damping member arranged between said two supporting members, said damping member comprising a fluidizable damping material injected into a space formed between said two supporting members and retained in position between said two supporting members by surface tension,
- wherein said two supporting members are formed such that the amplitude and/or phase of a vibration at neighboring portions of the two supporting members are shifted.
- 7. A method of manufacturing an apparatus for supporting an optical system in an apparatus for recording and/or reproducing information on and/or from an optical record medium, said apparatus comprising an optical system holding member for holding the optical system such that the optical system is opposed to said optical record medium, a stationary member provided on a carriage which is movable in a given direction with respect to the optical record medium, a supporting means for supporting said optical system holding member movably in at least one direction with respect to said stationary member and including at least two independent supporting members having a uniform length and spaced apart at a predetermined height therebetween, said two supporting members having first ends and second ends offset in a radial direction with respect to the optical recording medium, and said two supporting members having said first ends secured to said optical system holding member and said second ends secured to said stationary member, and a damping member provided between said two supporting members, said method comprising the steps of:
- injecting a fluidizable damping material into a space formed between said two supporting members of the supporting means; and
- retaining the injected fluidizable damping material in position between a main portion of said two supporting members by surface tension.
- 8. A method according to claim 7, wherein said method further comprises, after injecting said fluidizable damping material into said space, a curing step of curing said injected fluidizable damping material to form said damping member.
- 9. A method according to claim 8, wherein said curing step is performed such that said injected fluidizable damping material is transformed into a gel like damping member.
- 10. A method according to claim 8, wherein said curing step is performed such that said injected fluidizable damping material is transformed into a silicone rubber like damping member.
- 11. A method according to claim 8, wherein said fluidizable damping material is made of a thermo-setting material, and said curing step is performed by heating the damping material.
- 12. A method according to claim 8, wherein said fluidizable damping material is made of an UV-curable material, and said curing step is performed by irradiating the damping material with ultraviolet radiation.
- 13. A method according to claim 7, wherein said fluidizable damping material is injected into said space via an opening formed in one of the two supporting members.
- 14. A method according to claim 7, wherein said surface tension is directly between and in sole contact with said two supporting members.
