[embodiment]
See also Fig. 1, the utility model integrated information data recording/reproducing device 10 comprises a disc driver 11, a CD-ROM drive 12 and a rotating shaft 13.This rotating shaft 13 can be selected and incompatible control disc driver 11 or CD-ROM drive 12 work that match of disc driver 11 or CD-ROM drive 12.
This disc driver 11 comprises the disk 111 of a recorded information and the magnetic read/write head 112 that a pair of this disk 111 carries out information recording/regenerating.This disk 111 is a disc structure, and it has a center pit 113.The first surface 114 and one that this disk 111 has a recorded information is the second surface 115 of recorded information not, and magnetic read/write head 112 is positioned on the first surface 114 of disk 111.
CD-ROM drive 12 comprises the CD 121 of a recorded information and the optical read/write head 122 that a pair of this CD 121 carries out information recording/regenerating.This CD 121 is a disc structure, and it has a center pit 123.The first surface 124 and one that this CD 121 has a recorded information is the second surface 125 of recorded information not, and optical read/write head 122 is adjacent with the first surface 124 of CD 121.
This disk 111 and CD 121 are arranged mutually parallel, and disk 111 is relative with the second surface 115,125 of CD 121.This rotating shaft 13 is between disk 111 and CD 121, and the axis of its axis and disk 111 and CD 121 coincides.This rotating shaft 13 can be moved between disk 111 and CD 121 along axis direction.
Rotating shaft 13 comprise a rotating shaft body 131 and from the two ends of this rotating shaft body 131 along outward extending first turntable 132 of axis direction and second turntable 133.This rotating shaft body 131, first turntable 132 and second turntable 133 are all cylindrical structure.The radius of rotating shaft body 131 carries disk 111 and CD 121 greater than the radius of first turntable 132 and second turntable 133 to form a step respectively.The radius of first turntable 132 and second turntable 133 radius with the center pit 113,123 of disk 111 and CD 121 respectively is identical.The height of first turntable 132 and second turntable 133 is a bit larger tham the thickness of disk 111 and CD 121 respectively.The end of first turntable 132 and second turntable 133 has a plurality of equally distributed grooves 142 (groove on second turntable 133 is not shown) respectively.
Consult Fig. 2 and Fig. 3 simultaneously, be respectively the partial enlarged drawing and the vertical view of rotating shaft.A plurality of grooves 142 are radially outwards dispersed from a central shaft 143 of rotating shaft 13 and are arranged, and the end of each groove 142 has a ball 144, and this ball 144 partly stretches out the periphery of first turntable 132.Each groove 142 all holds a spring 145, and this spring 145 is between this central shaft 143 and ball 144.This ball 144 can move along the radial direction of first turntable 132, and it moves by 1322 restrictions of the projection on first turntable 132 along first turntable, 132 axial directions.When being subjected to external force, ball 144 does the time spent, spring 145 is compressed ball 144 all is contained in the groove 142, when external force is removed, the restoring force of spring 145 outwards flicks ball 144, and because of groove 142 near the width of first turntable, 132 peripheries, one ends diameter less than ball 144, ball 144 can only partly stretch out the periphery of first turntable 132.
When rotating shaft 13 when disc driver 11 directions move, first turntable 132 of rotating shaft 13 is by the center pit 113 of disk 111, being positioned at the extruding that ball 144 on first turntable 132 is subjected to center pit 113 edges moves to central shaft 143 directions, thereby make the turntable 132 of winning to pass through the center pit 113 of disk 111 smoothly, when the end face of first turntable 132 arrives the second surface 114 of disk, the effect that ball 144 is subjected to spring 145 restoring forces outwards flicks, thereby disk 111 is fixed in this rotating shaft 13.At this moment, when rotating shaft 13 when CD-ROM drive 121 directions move, ball 144 on first turntable 132 is subjected to the extruding at disk center pit 113 edges and moves to central shaft 143 directions, makes the turntable 132 of winning can pass through the center pit 113 of disk 11 smoothly, thereby disk 111 is separated with rotating shaft 13.
The structure of second turntable 133 is identical with the structure of first turntable 132, and it can make CD 121 match with rotating shaft 13 by identical mode.
See also Fig. 4, magnetic read/write head 112 comprises that two record-headers 151,152 and reproduce 153.Make magnetic read/write head 112 damages or make disk 111 sliding injuries for avoiding magnetic read/write head 112 and disk 111 to bump, this magnetic read/write head 112 also comprises an inclined guide mechanism 154.This inclined guide mechanism 154 record-header 151,152 and reproduce 153 with disk 111 between, it is used for leader record head 151,152 and reproduction 153 and contacts with disk 111.
See also Fig. 5 and Fig. 6, it discloses the structure and the index path of realizing CD 121 (CD and DVD) information recording/regenerating of CD-ROM drive 12, and wherein the CD of Fig. 5 is CD (having an information recording layer 165), and the CD of Fig. 6 is DVD (having an information recording layer 166).This optical read/write head 122 comprises one integration laser/receiver 161, collimation lens 162, a reflecting prism 163 and object lens 164.The laser that the laser instrument of this integration laser/receiver 161 sends becomes directional light by collimation lens 162 and is incident to reflecting prism 163, and reflecting prism 163 changes light paths makes laser be incident to object lens 164, object lens 164 with laser focusing on CD 121.After being reflected by CD 121, this laser transfers to the receiver of integration laser/receiver 161 successively by object lens 164, reflecting prism 163 and collimation lens 162.This integration laser/receiver 161 is a single-chip dual laser/receiver, and it can launch/receive two kinds of different wavelength of laser.
Because of the information recording layer 165 of CD different with information recording layer 166 residing position in CD 121 of DVD, for making 10 couples of CD of this integrated data recording/reproducing device and DVD energy compatible, the laser of two wavelength can be launched/be received to this integration laser/receiver 161, so that read/get different discs.(consult Fig. 5) when CD is CD, optical recording/reproduction 122 employing wavelength are that the laser of 780nm carries out recoding/reproduction to CD, and laser focuses on the information recording layer 165 of CD.(consult Fig. 6) when CD is DVD, optical recording/reproduction 122 employing wavelength are that the laser of 650nm carries out recoding/reproduction to DVD, and laser focuses on the information recording layer 166 of DVD.
See also Fig. 7, it has disclosed the principle of work of this integrated information data recording/reproducing device 10.Control circuit sends the order (step 191) of choosing memory storage, is information recording/regenerating disk (step 192) if this is ordered, and then rotating shaft moves up (step 193), and this rotating shaft matches with disk and rotates (step 194) with first rotating speed.The magnetic read/write head is realized recording of information/reproduction (step 198) to disk simultaneously.Be information recording/regenerating CD (step 195) if this is ordered, then rotating shaft moves down (step 196), and this rotating shaft matches with CD and rotates (step 197) with second rotating speed.Optical read/write head is realized recording of information/reproduction (step 198) to CD simultaneously.
Integrated information data recording/reproducing device of the present utility model also can be fixed on disk or CD in the rotating shaft by other holding unit.As: can above the disk and below the CD magnetic component be set respectively, rotating shaft is made by metal material, and when the turntable of rotating shaft is arranged in the center pit of disk or CD, thereby this magnetic component and rotating shaft are adsorbed mutually disk or CD are sandwiched between the two.
