Definitions

  • the invention relates to a disk cartridge for protecting an optical disk outside and exposing it inside a disk drive unit, said cartridge comprising: a disk having an axis and being rotatably disposed within said cartridge, said disk having two parallel surfaces, at least one of which contains readable data; and a housing having a top and a bottom with main surfaces substantially parallel to the surfaces of the disk, said housing having at least two parts which are mutually rotatable about an axis parallel to the axis of the disk in order to selectively move said housing parts between a closed position covering the disk and an open position exposing at least a portion of at least one of the surfaces of the disk.
  • Disk cartridges are known in various embodiments, such as the widely known
  • the housing of the cartridge gives the disk-cartridge combination a larger volume then a disk alone, so that it takes up more space in a disk drive unit than a disk alone.
  • the object of the present invention is therefore to provide a disk cartridge which assists in miniaturising the disk drive unit.
  • the cartridge according to the invention is characterized in that the housing parts are constructed such that said at least one surface of the disk is exposable over at least half its surface area.
  • the housing parts are constructed such that said at least one surface of the disk is exposable over at least half its surface area.
  • the cartridge therefore does not obstruct movements of the optical or other means scanning the surface of the disk at close range.
  • the axis of rotation of the housing parts coincides with the axis of the disk. This minimizes the space required in the disk drive unit as a result of the rotation of the housing part(s).
  • said housing parts comprise an outer housing part covering a portion of the disk on both sides, and an inner housing part covering another portion of the disk in the closed position and adapted to be rotated into the outer housing part when rotated to the open position, wherein preferably the inner housing part covers said other portion of the disk on both sides.
  • the cartridge may comprise two housing parts, each covering substantially half of the disk, while the inner housing part is adapted to be rotated substantially completely into the outer housing part, whereas in alternative embodiments a disk cartridge may comprise at least three housing parts, each covering a segment of the disk.
  • At least one of the housing parts may comprise a non- circular outer circumference. This feature may facilitate the proper orientation of the cartridge when it is being loaded into the disk drive unit. Of course it will be possible to have other orientation means either at the circumference or on the sides of the cartridge.
  • the housing parts in their fully open position, are separable from the disk, preferably in radial direction.
  • a space in the disk drive unit may then be reserved for occupying the separated housing parts of the cartridge.
  • the invention also relates to a disk drive unit adapted to receive the disk cartridge according to the invention.
  • Figs. 1 A-D are very schematic plan views of a first embodiment of the disk cartridge according to the invention, in four different positions.
  • Figs. 2 A-D are very schematic bottom views of the disk cartridge of Fig. 1 in similar positions.
  • Fig. 3 is a larger-scale cross-sectional view of half of the disk cartridge of Fig. 1 taken on the line III-III in Fig. 1 D.

  • Figs. 10 A-D, 11 A-D, and 12 are views corresponding to those of Figs. 1-3, but showing a fourth embodiment of the disk cartridge according to the invention.
  • Fig. 13 is a very schematic cross-section of a disk drive unit.
  • Fig. 14 is a very schematic section taken on the line XIN-XIV in Fig. 13.
  • FIG. 1 show several embodiments of a disk cartridge containing a small disk 1, particularly a so-called small form factor optical disk (SFFO disk).
  • This disk 1 is relatively rigid and will typically have a diameter of 30 mm, although other diameters are conceivable.
  • This disk 1 may be used in optical disk drive units, for example used in portable equipment, such as mobile telephones, PDAs, and the like.
  • the cartridge is adapted to protect the optical disk 1 outside and to expose it inside a disk drive unit.
  • the disk 1 has an axis of rotation 2 and a clamping area 3 with which a spindle of a drive unit can engage in order to drive the disk 1.
  • the disk 1 In order to be driven, the disk 1 is rotatably disposed within the cartridge.
  • the disk 1 comprises two parallel surfaces and at least a surface 4 contains readable data.
  • the cartridge further comprises a housing 5, in this case consisting of two housing parts 6 and 7 which are mutually rotatable about an axis which coincides with the axis of rotation 2 of the disk 1.
  • the housing 5 has a top and a bottom with main surfaces which are substantially parallel to the surfaces of the disk.
  • Each housing part 6, 7 is shaped as a circular segment and, in this case, extends through appr. 180° to form two semicircular flat box-shaped parts.
  • Both the housing parts 6 and 7 have a top and a bottom wall 6a, 6b and 7a, 7b, respectively, connected by a circumferential edge 6c, 7c.
  • the outer dimensions of the housing part 7 are substantially similar to or slightly smaller than the inner dimensions of the outer housing part 6, so that the inner housing part 7 is adapted to be rotated into the outer housing part 6 when it is rotated from the closed position covering substantially half of the optical disk into an open position in which it exposes said half of the disk 1.
  • the housing parts 6, 7 may comprise guiding means to facilitate these rotational movements of the housing parts 6, 7.
  • the inner dimensions of the inner housing part 7 are slightly larger than the dimensions of the disk, so that the disk 1 is capable of rotating.
  • the thickness of the housing 5 of the cartridge should be made as small as possible, while still leaving room between disk 1 and the housing parts 6, 7 at least at the surface 4 of the disk 1 containing the data.
  • the inner housing part 7 and the disk drive unit comprise a member and a counter member which co-operate in order to automatically move the inner housing part 7 into the open position (Figs. Id, 2d) when it is being introduced into and into the closed position (Fig. la, 2a) when it is removed from the drive unit.
  • Figs. 13 and 14 show such a disk drive unit comprising a motor 8 and a spindle 9, as well as optical means 10 for reading the data of the disk 1.
  • the cartridge is shown as being inserted into the drive unit.
  • the housing part 7 is rotated into the housing part 6 and has exposed substantially half of the disk 1.
  • the disk 1 has its clamping area 3 engaged by the spindle 9 of the motor 8 in order to be driven.
  • the head 11 of the optical means 10 is positioned very close to the disk 1 when inserted, which is made possible by the cartridge housing 5 which exposes at least substantially half of the disk surface area to make room for the optical means.
  • Figs. 13 and 14 show such a disk drive unit comprising a motor 8 and a spindle 9, as well as optical means 10 for reading the data of the disk 1.

  • FIG. 4a shows a second embodiment of the disk cartridge according to the invention, which comprises four housing parts 12-15, each being formed as circular segments of 90°.
  • Housing part 12 is the outer housing part and all further housing parts are slightly smaller (Fig. 4a) so that, starting from the housing part 15, all housing parts fit into the next one (Figs. 4b and 4c) and, in the fully open position, all housing parts coincide so that almost 3/4 of the surface area of the disk 1 is exposed.
  • the thickness of the outer housing part 12 will be greater than that of the housing part 6 in the first embodiment, but the surface area of the set of housing parts 12-15 will be smaller.
  • the cartridge will comprise locking means which prevent a mutual rotation of the housing parts outside the disk drive unit to provide a safe protection of the disk 1. Only in the disk drive unit will such a locking be released by means of the disk drive unit in order to expose the surface 4 of the disk 1 to the optical means 10 of the drive unit.
  • Figs. 7-9 show a further embodiment of the disk cartridge, now comprising seven housing parts 16-22, each covering substantially 1/7 of the disk surface area.
  • the principle of opening and closing of the cartridge is similar to that in the former embodiment, with two differences. First of all, the direction of rotation of housing parts 17-19 is opposed to that of housing parts 20-22 (Figs. 7b,c, and ' 8b,c) but they all come together within the outer housing part 16.
  • a second difference is that the housing 5 is constructed such that it is separable from the disk 1. This separation will take place upon insertion of the disk cartridge into the disk drive unit. This separation is illustrated in Figs. 7d and 8d.
  • the set of housing parts 16-22 will be stored in a location in the disk drive unit reserved for this and, upon removal of the disk 1 from the disk drive unit, it will be connected again to the housing parts 16-22, and the disk 1 will be completely covered again by the housing parts when outside the disk drive unit.
  • Figs. 10-12 shows a variation of the embodiment of Figs. 1-3 as regards the shape of the outer housing part 6'.
  • the outer housing part 6' is of non- circular shape, i.e. is rectangular to improve the orientation of the cartridge with respect to the drive unit when the disk cartridge is inserted into the opening of the disk drive unit.
  • the outer housing part 6' may be of other shapes such as square or a triangular shape. This is also true for the other embodiments, as long as the inner housing parts are able to be rotated into the outer housing part.
  • the disk may also contain data in another form so that it is read in another way than optically.
