Claims12
A recording and reproducing apparatus having a holder for holding a cartridge with a recording medium stored therein in which said recording medium is loaded on or unloaded from a recording and reproducing position for recording and/or reproducing said recording medium, comprising:
- driving means on which said recording medium rests and which drives said recording medium for recording and/or reproduction at said recording and reproducing position;
- and
- elevating means having a cam for elevation provided on its side portion and elevating and lowering said holder relative to said recording and reproducing position when said elevating means is slid in parallel to an insertion direction of said cartridge, wherein said elevating means includes first and second slide members each having a cam groove defined on its side surface and said first and second slide members are coupled with a predetermined clearance such that they are capable of being finely moved relative to each other wherein the elevating means is configured to elevate said driving means relative to said recording medium such that said recording medium rests on said driving means, and further comprising a first elevating member with said driving means attached thereto and a second elevating member for rotatably supporting said first elevating member and which is elevated together with said first elevating member as said elevating means is slid.
A disk drive, comprising:
- a holder for holding a disk cartridge inserted thereto;
- a slider engaged with said holder and slid for loading and unloading said disk cartridge to and from a recording and/or reproducing position;
- and
- a motor having a chucking member on which a disk stored within said disk cartridge loaded at said recording and/or reproducing position rests and configured to rotate said disk;
- wherein said slider includes first and second slider members coupled together with a predetermined clearance such that they can be finely moved further comprising elevating means for elevating said chucking member, and said elevating means comprises a first elevating member with said motor attached thereto and a second elevating member being elevated and lowered together with said first elevating member as said slider is slid.
A disk drive, comprising:
- a holder for holding a disk cartridge inserted thereto;
- a slider engaged with said holder and slid for loading and unloading said disk cartridge to and from a recording and/or reproducing position;
- a motor having a chucking member on which a disk stored within said disk cartridge loaded at said recording and/or reproducing position rests and configured to rotate said disk;
- an elevating member for elevating said chucking member, said elevating member including a first elevating member with said motor attached thereto and a second elevating member being elevated and lowered together with said first elevating member as said slider is slid;
- and
- a supporting shaft for rotatably supporting said first elevating member to said second elevating member, said supporting shaft engaged with an inclined portion of said slider;
- wherein said slider includes first and second slider members coupled together with a predetermined clearance such that they can be finely moved.
