Description

  The present invention relates to a disc tray device and a recording / reproducing device including the disc tray device. More specifically, the present invention conveys an optical disc, which is a disc-type recording medium, and writes information to and reads information from the optical disc. The present invention relates to a disc tray apparatus and a recording / reproducing apparatus including the disc tray apparatus.

  Optical discs that record / reproduce information using light such as CDs and DVDs have become widespread. In addition, BD (blu-ray disk) and HD DVD (High Definition DVD) have appeared on the market as large-capacity optical disks, and are expected to spread in the future. A disk tray device is provided as a device for writing information on such an optical disk and reading information. The disc tray device has a tray on which an optical disc is set. The tray is loaded and the optical disc is transported to a predetermined position so that information can be written to and read from the optical disc by an optical pickup provided in the disc tray device. Can be executed.

  In the disc tray device as described above, the optical disc is set on the tray at a position where the tray is pulled forward from the inside of the device. When the tray is loaded into the apparatus, the optical disk is chucked at the predetermined position. At the time of chucking, a convex portion formed at the center of the turntable that holds and rotates the optical disc is inserted into a hole in the center of the optical disc, and at the same time, the clamper approaches from the upper surface side of the optical disc. Chucked on the table. When taking out the optical disk, the above-mentioned clamper and turntable are detached from the optical disk, and the tray is pulled forward.

  8 and 9 are diagrams for explaining an example of the clamping operation of the conventional disc tray device as described above. FIG. 8 is a diagram when the optical disc is chucked on the turntable at the chucking position. FIG. 9 is a diagram showing a state when the chucking state of FIG. 8 is released and the light disk is taken out (or when the pulled-out tray is set at the chucking position). In this example, an example in which a BD optical disk housed in a cartridge having openings on the upper surface and the lower surface (back surface) is used is shown.

  8 and 9, 1 is a base chassis, 2 is a turntable that holds and rotates an optical disk, 3 is a spindle motor that controls the rotation of the turntable, 6 is a traverse chassis in which the spindle motor 3 is installed, 10 Is a tray for carrying the optical disk, 14 is a tray cam portion for displacing the clamper according to the movement of the tray, 30 is a clamper for clamping the optical disk, 31 is a clamper lever for operating the clamper, and 32 is a clamper and clamper. A clamper plate mounted with a lever, 33 is a clamper lever support shaft on which the clamper lever is rotatably supported with respect to the clamper plate, 34 is an urging spring for urging the clamper lever, 40 is an optical disc, and 42 is an optical disc. Cart Tsu di.

  The clamper lever 31 is rotatably installed by a clamper lever support shaft 33, and the clamper 30 provided in the vicinity of the tip of the clamper lever 31 swings and displaces with the rotation operation. Further, the traverse chassis 6 also swings in accordance with the forward / backward movement of the tray 10, and the spindle motor 3 installed on the traverse chassis 6 and the turntable 2 installed on the spindle motor 3 operate integrally. .

  The tray 10 is provided with a tray cam portion 14, and in the state of FIG. 8, the end of the clamper lever 31 on the back side of the tray contacts the tray cam portion 14, the clamper lever 31 rotates, and the biasing spring 34 The clamper 30 is pushed down in a form against the urging force. Further, at the position of FIG. 8, the traverse chassis 6 is displaced upward, and the convex portion of the turntable 2 is inserted into the hole in the center of the optical disc 40. In this state, the optical disc 40 is chucked between the convex portion of the turntable 2 and the clamper 30. Since the clamper 30 is rotatably provided, the clamper 30 does not impede the rotation even when the optical disc 40 rotates at a high speed as the turntable 2 is rotated by driving the spindle motor 3.

  In the state of FIG. 9, the tray cam portion 14 of the tray 10 is separated from the end of the clamper lever 31, and the clamper lever 31 is rotated by the urging force of the urging spring 34, and the clamper 30 is detached from the optical disk 40 and moved upward. Displace. Further, as the tray 10 moves, the traverse chassis 6 swings and is displaced downward so as not to prevent the optical disc 40 from being conveyed.

  Many of the optical disks used in the disk tray apparatus as described above are normally distributed as bare disks that are not accommodated in cartridges. DVD-RAM and BD are distributed as cartridge disks housed in cartridges. For example, some DVD-RAM cartridges are provided with openings on the front and back sides so that access to the recording / reproducing apparatus and optical disc clamping can be executed by the openings. In addition, BD currently offers cartridge disks housed in cartridges, but in the near future, bare-type BDs are expected to appear on the market. The current BD cartridge is a type with a built-in clamper, and has a shutter that can be opened and closed on the back surface (recording layer side), or the front surface is closed and a shutter is provided on the back surface.

  Thus, for example, when a cartridge type and a bare type coexist in BD, some DVDs, etc., the disc tray device corresponding to these optical disc media is required to be able to use any type of disc. .

In response to the above request, for example, in Patent Document 1, in a transport mechanism capable of transporting both a cartridge disk and a bare disk, the clamper is allowed to escape upward to a position where the clamper does not hit when the cartridge disk is transported. Further, there is disclosed a configuration in which the transport mechanism is made thin by rotating the holder member of the clamper and pressing the clamper against the disk medium.
Japanese Patent Laid-Open No. 10-312628

  As described above, in the disk tray device that transports the disk tray, there is a demand to be able to cope with both the cartridge disk and the bare disk. In this case, the optical disk is set horizontally (the recording surface is in the horizontal direction). It is further required to be compatible with not only the horizontal type but also the vertical type in which the optical disk is set vertically (the recording surface is in the vertical direction).

In the case of exclusive use for a bare disk without a cartridge, for example, by installing a claw part for supporting the optical disk on the tray, the optical disk can be loaded while being held by the claw part.
At this time, at the chucking position of the optical disc, if the claw portion comes into contact with the optical disc as the optical disc rotates, it causes a trouble.

  In order to cope with this, the position of the claw portion is set so that the optical disk is placed slightly below the normal chucking position of the optical disk. When the optical disk held by the claw is conveyed by the tray and chucked by the turntable and the clamper, if the tip of the convex part of the turntable can enter the central hole of the optical disk, the convex part is formed. The tapered portion can lift the optical disc upward, and the optical disc can be separated from the claw portion.

  10A and 10B are diagrams schematically showing a clamp portion by a clamper and a turntable. FIG. 10A is a diagram showing a state before the optical disk is clamped, and FIG. 10B is a diagram showing a state after the clamp. . As shown in FIG. 10, the turntable 2 is provided with a convex portion 2 a that is inserted into the central hole 40 a of the optical disc 40. The convex portion 2a is formed with a taper t. Even if the centers of the turntable 2 and the optical disc 40 are slightly shifted from each other, if the tip of the convex portion 2a can be inserted into the central hole portion 40a, the convex portion 2a is formed. The position of the optical disk 40 can be corrected by the taper t, and the optical disk 40 can be chucked at a predetermined position.

  If the height of the convex portion 2a is sufficiently high and the area of the tip of the convex portion 2a is relatively small to form a gentle taper t, the position is relatively far from the position where the optical disk 40 is chucked. Even when the optical disk 40 is loaded, the optical disk 40 can be chucked at the regular position.

That is, when holding a bare type optical disk (bare disk) using the claw portion as described above, by setting the bare disk to be lifted upward by the convex portion 2a of the turntable 2, the chucked bear The disc and the claw portion are separated from each other so that the claw portion does not hinder the high-speed rotation of the bare disc.
In this way, the vertical-type disc tray device dedicated to the bare type can execute the loading and unloading operations of the optical disc relatively easily.

However, in order to enable the combined use of the cartridge type and the bare type as in the above-described BD, there is a problem with the above configuration.
For example, in the cartridge disk, the height of the convex portion 2a of the turntable 2 is limited due to the limitation of the allowable space in the thickness direction of the cartridge, and the height of the convex portion 2a is sufficiently high. Can not. That is, in order to correspond to the cartridge disk, it is not possible to take a large taper of the convex portion used in a bare type dedicated device of DVD, and the chucking stability and the contact with the holding member of the optical disk It becomes difficult to achieve both avoidance.

For example, when the optical disk is held vertically, it is necessary to support the optical disk at a plurality of support points or a certain support area. At this time, in the convex portion 2a whose height is limited to correspond to the cartridge type, if attention is paid to a part of the support points and a part of the narrow support area, the radius of the optical disk with respect to the support points and the support areas is reduced. By moving in the direction, a sufficient interval can be formed. However, since the optical disk does not move in the radial direction at other support points or support regions, a sufficient interval cannot be formed. Conversely, if the positions of the support points and regions are set in advance in order to obtain sufficient intervals at a plurality of support points and a certain area, chucking itself is performed due to the height restriction of the convex part of the turntable. I can't do that.
Further, when a bare disk holding portion, guide, or the like is provided on the tray, the above-described holding portion or guide protrusion cannot be provided in a space for setting a cartridge disk having a larger outer shape than the bare disk.

  Further, the above Patent Document 1 does not disclose a disk tray device that can deal with the bare disk and the cartridge disk as described above and can be applied to the vertical use.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a disc tray device that can be used in combination with a bare disc and a cartridge disc and that can be applied to a vertical type.

  The first technical means includes a turntable for chucking the optical disk, and a tray for transporting the optical disk between a discharge position where the optical disk can be discharged and a chucking position where chucking is performed. In the disc tray device that writes information to and / or reads information from the optical disc, the disc tray device holds the bare type optical disc when the recording surface of the optical disc is used in a vertical orientation in a vertical direction. The first member holds the optical disk when the optical disk is transported between the ejection position and the chucking position, and does not contact the optical disk when the optical disk is chucked. It is characterized in that it is displaced.

  According to a second technical means, in the first technical means, the disk tray device has a traverse chassis on which a turntable is installed. The traverse chassis is displaced according to the transporting operation of the tray, and the optical disk is chucked. The first member is mounted to be displaceable on the tray so that the traverse chassis approaches the optical disc when the traverse chassis approaches the optical disc. The pressing portion provided on the pressing member presses the first member, and the first member is displaced so as not to contact the bare type optical disc.

  The third technical means includes a biasing member that biases the first technical member in a direction to return to a position where the first member holds the bare type optical disc in the second technical means, and the pressing portion pushes the first member. When the pressing member moves away from the first member with the operation of the traverse chassis in a state where the first member is displaced by the pressing, the first member holds the bear type optical disk by the biasing force of the biasing member. It is characterized by returning to a position.

  According to a fourth technical means, in the third technical means, the first member holds and holds the cartridge while being displaced on the tray by being pressed by the cartridge of the optical disk when the cartridge type disk is used. When the cartridge-type optical disk is removed from the state, it returns to the position for holding the bare-type optical disk by the urging force of the urging member.

  A fifth technical means is the technical means according to any one of the first to fourth technical means, wherein the disc tray device holds a bare type optical disc when used in a vertical orientation in which the recording surface of the optical disc is vertical. When the surface of the tray on which the optical disk is installed when the disk tray device is used in the horizontal orientation is used as the optical disk installation surface, the second member is located on the optical disk side from the optical disk installation surface. It is configured to be able to take two positions: an optical disk holding position that protrudes and holds a bare type optical disk, and a retracted position that retreats backward from the optical disk installation surface. When using a cartridge type optical disc, set the second member in the retracted position. Is obtained by it said.

  According to a sixth technical means, in the fifth technical means, the turntable has a convex portion to be inserted into the central hole of the optical disc, and the convex portion has a convex top portion as compared with the area of the chucking position of the optical disc. When the convex portion is inserted into the bare type optical disc held by the second member and chucking is performed, the convex portion is inserted. When the optical disk moves away from the second member due to the taper and chucking is completed, the interval between the second member and the bare type optical disk is widened to a distance that does not hinder the rotation of the optical disk. It is characterized by being configured.

  The seventh technical means includes the disc tray device of any one of the first to sixth technical means, and performs recording of information on the optical disc conveyed by the disc tray device and reproduction of information recorded on the optical disc. It is characterized by that.

According to the present invention, it is possible to provide a disc tray device that can be used in combination with a bare disc and a cartridge disc, and that can be applied to the vertical type, and a recording / reproducing device including the disc tray device.
That is, according to the present invention, even when the disc tray device is used in a vertical position, the optical disc is stably held so that the optical disc does not fall off the tray when loading the optical disc, and the optical disc is chucked on the turntable. Can be executed stably. Further, since the member for holding the disc is displaced during chucking, the optical disc can be driven stably without hindering the rotation of the optical disc.

Embodiments of a disk tray apparatus according to the present invention will be specifically described below with reference to the accompanying drawings. Note that in all the drawings for explaining the embodiments, the same reference numerals are given to portions having similar functions, and repeated explanation thereof is omitted.

The first pressing lever 11 corresponds to the first member of the present invention, and the disc holder 13 corresponds to the second member of the present invention.

  FIG. 1 shows a state in which the tray 10 is loaded inside the base chassis 1. When the tray transport mechanism provided on the base chassis 1 operates, the tray 10 is pulled out in the direction of arrow A, and the user can set the optical disk. When the tray transport mechanism is operated again, the optical disk is loaded into the base chassis 1 together with the tray 10. When ejecting the optical disk, the tray 10 is pulled out in the direction of arrow A again.

  In practice, a clamper plate (not shown) is attached to the main chassis 1 in FIG. 1, and a clamper provided on the clamper plate operates to clamp the loaded optical disk with the turntable (chucking). ) In this state, the optical pickup 4 can write data to the optical disc and read data from the optical disc. That is, it can be said that the tray 10 conveys the optical disk between a discharge position where the optical disk can be discharged and a chucking position where the optical disk is chucked.

2 and 3 are diagrams for explaining the tray advancing / retreating operation and the accompanying optical disk chucking operation by the clamper and the turntable. FIG. 2 is an optical disk chucking operation during the tray loading operation. FIG. 3 is a schematic side view showing a state where the optical disc is not loaded when the tray is loaded and the optical disk is chucked. Figure).
2 and 3, 6 is a traverse chassis in which the spindle motor 3 to which the turntable 2 is attached is installed, 7 is a cartridge stay for supporting the cartridge disk, 30 is a clamper for clamping the optical disk, and 31 is a clamper. A clamper lever for operation, 32 is a clamper and a clamper plate on which the clamper lever is mounted, and 33 is a clamper lever support shaft on which the clamper lever is rotatably supported with respect to the clamper plate.

  When the tray 10 is pulled out from the base chassis 1, the optical disk 40 is set in the tray 10, and the tray 10 moves again into the base chassis 1, a tray cam portion provided in the tray 10 as shown in FIG. 2. 14 abuts against the end of the clamper lever 31 on the back side of the tray. When the tray 10 further advances (in the direction of arrow B) and reaches a predetermined loading position, the clamper lever 31 rotates around the clamper lever support shaft 33 as shown in FIG. It is displaced in the direction of 10.

At the same time, the traverse chassis 6 separated from the tray 10 as shown in FIG. 2 by the movement of the tray 10 is displaced toward the tray 10 as shown in FIG. 3 when loading is completed.
Thus, when loading shown in FIG. 3 is completed, the optical disk is clamped between the turntable 2 and the clamper 30, and the chucking operation is completed.

  When the chucking of the optical disc 40 is released and the tray 10 is pulled out, the action of the tray cam portion 14 on the clamper lever 31 is released, the clamper lever tries to return to the original state by the biasing force of the spring, and the clamper 30 is detached from the optical disc 40. To be displaced. In addition, when the tray 10 is pulled out, the traverse chassis 6 is displaced in a direction in which it is detached from the tray 10 so that the conveyance of the optical disc 40 is not hindered.

  The optical disk shown in FIGS. 2 and 3 is a cartridge disk having an opening on the front surface and the back surface, or a front surface opening and a back surface that can be opened and closed by a shutter mechanism. The optical disk 40 is chucked by the clamper 30. can do. At this time, if the back surface has a shutter mechanism, the shutter opening / closing mechanism 5 shown in FIG. 1 opens / closes the shutter according to the movement of the tray 10.

  Even when a bare disk is used, the optical disk 40 can be chucked by the clamper 30 by the operation of the clamper lever 31 and the traverse chassis 6 as described above. Further, when a cartridge type in which the front surface of the optical disk is not opened is used, even if the tray cam portion 14 contacts the clamper operation mechanism, the displacement of the clamper 30 is stopped and the chucking of the optical disk 40 is not hindered. ing. In this case, the optical disk 40 is chucked by the clamper built in the cartridge and the turntable 3.

  The operation mechanism of the clamper that accompanies the loading operation of the tray 10 as described above is not limited here, and a clamper configuration that can use both the bear type and the cartridge type may be provided.

  FIG. 4 is a schematic perspective view for explaining the configuration and operation of the tray 10 in more detail, and shows an example in which a bare disk 41 is set on the tray 10 as an optical disk. The bare disk 41 corresponds to the cartridge type optical disk 40 described above. In FIG. 4, 11 is a first pressing lever, 12 is a second pressing lever, 11a and 12a are bare disk pressing claws, 11b and 12b are rotating shafts, 11c and 12c are cartridge disk pressing parts, and 11d is a bare disk. A disk holding portion, 11e is a protrusion, 13 is a disk holder, and 15 is a cartridge stay through-hole for advancing and retracting a cartridge stay for positioning the cartridge disk.

When using the bare disk 41, the disk holder 13 is used to hold the bare disk 41. The disk holder 13 is pivotally supported by a holder rotation shaft 13a and is provided to be rotatable with respect to the tray 10. When a normal cartridge disk is used, the disk holder 13 can be retracted toward the back of the tray 10 so that the setting of the cartridge disk is not hindered.
When the bare disk 41 is used, the disk holder 13 is pulled out to form as shown in FIG. 4, and the bare disk 41 is held in contact with the upper side wall portion.

  That is, when the surface of the tray on which the optical disc is installed when the disc tray device is used in the horizontal orientation is the optical disc installation surface, the disc holder 13 protrudes from the optical disc installation surface toward the optical disc and holds the bare disc. It is configured to be able to take two positions, a holding position and a retracted position that retracts backward from the optical disk installation surface. When using the bare disk 41, the disk holder 13 is set at the optical disk holding position, and when using a cartridge disk, the disk holder 13 is set at the retracted position. Switching between the optical disk holding position and the retracted position is manually performed by the user, but some automatic switching mechanism or a mechanism for switching these according to an instruction from an operation button or a remote controller may be added.

The other part that holds the bare disk 41 is a bare disk holding part 11 d that protrudes from the first pressing lever 11. The bare disk 41 is supported from below by the disk holder 13 and the bare disk holding portion 11 d of the first pressing lever 11.
Further, the bare disk pressing claw portion 11a of the first pressing lever 11 and the bare disk pressing claw portion 12a of the second pressing lever 12 have a function of holding the bare disk 41 so as not to fall down.

  When a cartridge disk is used, the disk holder 13 is rotated toward the back side of the tray 10 as described above, and then the cartridge disk is set on the tray 10. Here, the first pressing lever 11 is rotatably provided on the tray 10 by the rotating shaft 11b. When the cartridge disk is set on the tray 10, the first pressing lever 11 is in the direction of the arrow D. The cartridge disk pressing portion 11c contacts and holds the cartridge disk.

  Similarly, the second pressing lever 12 is rotatably provided on the tray 10 by the rotating shaft 12b. When the cartridge disk is set on the tray 10, the second pressing lever 12 is moved to the arrow C. The cartridge disk pressing portion 12c comes into contact with and holds the cartridge disk.

  In the present embodiment, when the bare disk 41 is loaded while being set on the tray 10 and is chucked on the turntable 2, the disk holder 13 holding the bare disk 41 and the first pressing lever 11 Are separated from the bare disk 41 so that the high-speed rotation of the bare disk is not hindered. Here, of the first presser lever 11 and the disc holder 13 that support the vertically placed bare disc, the first presser lever 11 is displaced in the direction away from the bare disc during chucking. The lever 11 and the disc holder 13 are separated from the chucked bare disc. The configuration will be described below.

  First, the operation of the first pressing lever 11 will be described with reference to FIGS. 2, 3, 5 and 6. 5 and 6 are views for explaining the state in the vicinity of the first pressing lever 11, and FIG. 5 is a state in which the traverse chassis 6 is displaced in a direction away from the tray 10 as shown in FIG. FIG. 6 shows a state when the traverse chassis 6 is displaced toward the tray 10 and the optical disk is chucked as shown in FIG.

  As shown in FIGS. 2 and 3, the traverse chassis 6 is provided with a cartridge stay 7 for supporting the cartridge disk. When the cartridge disk is used, when the traverse chassis is displaced in the direction of the tray 10 and the chucking of the optical disk is completed, the top of the cartridge stay 7 comes into contact with the back surface of the cartridge disk, and the cartridge disk is positioned at a predetermined position. The cartridge stay 7 advances and retreats through a through hole 15 provided in the tray 10. At this time, in the state of FIG. 2, the top of the tray 10 is kept hidden behind the tray 10, but when the traverse chassis 6 is displaced in the state of FIG. 3, the top of the cartridge stay 7 passes through the through hole 15 and the tray 10. Come out on the front side. Thereby, the cartridge disk is positioned at a predetermined position.

In this embodiment, the cartridge stay 7 is used to displace the first pressing lever 11 that supports the bare disk when placed vertically during chucking so as not to prevent the rotation of the bare disk.
First, in the state of FIG. 2, the first pressing lever 11 is in a position for supporting the bare disk as shown in FIG. Since the cartridge stay 7 is provided on the traverse chassis 6 that is displaced according to the loading operation of the tray 10 as described above, in the state shown in FIG. It does not act on the 1 holding lever 11. In this state, the bare disk is held by the bare disk holding unit 11d, and the bare disk can be stably conveyed.

  Next, in the state of FIG. 3, the first pressing lever 11 rotates in a direction away from the bare disk (arrow D direction) so as not to inhibit the rotation of the bare disk as shown in FIG. 6. Here, with the displacement of the traverse chassis 6 provided with the cartridge stay 7, the top of the cartridge stay 7 passes through the through hole 15 and comes out to the front side (bare disk side) of the tray 10. At this time, as shown in FIG. 6, the top of the cartridge stay 7 abuts on the protrusion 11 e provided on the first pressing lever 11 and presses the protrusion 11 e as the cartridge stay 7 moves. To displace. This protrusion part 11e corresponds to the press part in this invention.

  When the protrusion 11e is pressed, the first pressing lever 11 rotates around the rotation shaft 11b in the arrow D direction. When the first pressing lever 11 is rotated, the bare disk holding portion 11d that has held the bare disk is separated from the bare disk, and the rotation of the chucked bare disk can be prevented from being affected.

  In the state shown in FIG. 3, when the tray starts to move in the ejection direction and the chucking of the optical disk is released, the traverse chassis 6 is displaced in the direction of separating from the optical disk, and the cartridge stay 7 is also detached from the protrusion 11e. Then, it moves to the back side of the tray 10. A spring is attached to the first pressing lever 11 as a biasing member that biases it back to a position where the bare disk can be held. As the traverse chassis is displaced, the first pressing lever 11 6 returns to the state of FIG. 5 from the state of FIG.

  Next, the disk holder 13 does not escape in the direction of detachment from the bare disk unlike the first pressing lever 11, but the bare disk moves upward in the radial direction during the chucking operation of the bare disk. A sufficient gap is formed between the disc holder 13 and the bare disc.

  As described above, when the cartridge disk and the bare disk are used in combination, the convex part of the turntable cannot be made sufficiently high. However, when the bare disk is chucked, if the bare disk moves in a substantially radial direction with respect to one support point of the bare disk, the distance between the support point and the bare disk can achieve an acceptable level. it can.

  Therefore, in this embodiment, the support points of the bare disk are the two points of the disk holder 13 and the first pressing lever 11, and the bare disk moves in the radial direction with respect to the disk holder 13 when chucking the bare disk. By setting so that the distance between the disk holder 13 and the bare disk is ensured, the first pressing lever 11 is rotated at the time of chucking in the above-described configuration, whereby the first holding lever 11 is rotated. An interval between the holding lever 11 and the bare disk can be secured.

  With the above configuration, the disc tray device of this embodiment can support both vertical placement of both types of cartridge discs and bare disc optical discs, and can perform bare disc tray installation, transport, and chucking operations. It will be possible to carry out with reliability without any trouble.

  In addition, a recording / reproducing apparatus can be provided by using the disk tray apparatus as described above. FIG. 7 is a diagram for explaining a configuration example of the recording / reproducing apparatus. The recording / reproducing apparatus 100 is configured so that a plurality of recording media can be properly used. For example, in the example of FIG. 7, the recording / reproducing apparatus 100 includes a BD recording / reproducing apparatus 101, a DVD recording / reproducing apparatus 102, and an HDD recording / reproducing apparatus 103, and these plural recording media can be selectively used. Yes. In addition, by providing the recording / reproducing apparatus 100 with a tuner unit, for example, content broadcast on television can be recorded on a recording medium. Also, processing such as data dubbing or moving between a plurality of recording media can be executed.

  The recording / reproducing apparatus 100 is provided with a disk tray device for setting a disk type recording medium. For example, in the example of FIG. 7, a DVD disk tray device and a BD disk tray device are individually provided. Thus, the user can use the respective disk tray devices to transport the corresponding recording media into the recording / reproducing apparatus.
