Description

この発明は、可撓性を有する記録ディスクを安定して走査する記録ディスク駆動装置及び可撓性を有し安定して走査できる記録ディスクを収納するディスクカートリッジに関する。   The present invention relates to a recording disk drive device that stably scans a flexible recording disk and a disk cartridge that houses a flexible recording disk that can be stably scanned.

近年、テレビ放送のデジタル化が始まるなど、大容量のデジタルデータを記録することが情報記録媒体に求められている。例えば、光ディスクの分野においては、記録再生のために光ディスクに集光される光スポット径を小さくすることが、高密度化のための基本的な方法の１つに挙げられる。   In recent years, there has been a demand for information recording media to record large volumes of digital data, such as the start of digitization of television broadcasting. For example, in the field of optical disks, one of the basic methods for increasing the density is to reduce the diameter of the light spot collected on the optical disk for recording and reproduction.

このため、光ディスクの高密度化においては、記録再生のために用いられる光の波長を短く、かつ対物レンズの開口数NAを大きくすることが有効である。光の波長についてはCD(compact disk)では近赤外光の780nm、DVD(digital versatile disk)では赤色光の650nm近傍の波長が用いられている。最近、青紫光の半導体レーザが開発され、今後は400nm近傍のレーザ光が使用されると予想される。   For this reason, in increasing the density of an optical disk, it is effective to shorten the wavelength of light used for recording and reproduction and increase the numerical aperture NA of the objective lens. As for the wavelength of light, a wavelength of near infrared light of 780 nm is used for CD (compact disk), and a wavelength of about 650 nm of red light is used for DVD (digital versatile disk). Recently, a blue-violet semiconductor laser has been developed, and it is expected that a laser beam of around 400 nm will be used in the future.

また、対物レンズについては、CD用はNA0.5未満であったが、DVD用はNA0.6程度である。今後、さらに開口数(NA)を大きくしてNA0.7以上とすることが求められる。しかし、対物レンズのNAを大きくすること、および光の波長を短くすることは、光を絞るときに収差の影響が大きくなることでもある。したがって、光ディスクのチルトに対するマージンが減ることになる。また、NAを大きくすることによって焦点深度が小さくなるため、フォーカスサーボ精度を上げなくてはならない。   As for the objective lens, it was less than NA0.5 for CD, but about NA0.6 for DVD. In the future, it is required to further increase the numerical aperture (NA) to NA 0.7 or more. However, increasing the NA of the objective lens and shortening the wavelength of light also increase the influence of aberrations when focusing light. Therefore, the margin for the tilt of the optical disk is reduced. In addition, since the depth of focus is reduced by increasing the NA, the focus servo accuracy must be increased.

さらに、高NAの対物レンズを使用することによって、対物レンズと光ディスクの記録面との距離が小さくなってしまうため、光ディスクの面ぶれを小さくしておかないと、始動時のフォーカスサーボを引き込む直前、対物レンズと光ディスクとが衝突することがあり、ピックアップの故障の原因となる。   Furthermore, using a high NA objective lens reduces the distance between the objective lens and the recording surface of the optical disc. The objective lens and the optical disk may collide, causing a pickup failure.

非特許文献１には、CDと同程度に厚く、かつ剛性の大きい基板に記録膜を成膜し、記録再生用の光を基板を通さずに、薄いカバー層内を通して記録膜に対して記録再生する、短波長、高NAの大容量光ディスクが提案されている。   In Non-Patent Document 1, a recording film is formed on a substrate that is as thick and rigid as a CD, and recording / reproducing light is recorded on the recording film through a thin cover layer without passing through the substrate. A large-capacity optical disk with a short wavelength and a high NA for reproduction has been proposed.

非特許文献１では、光ディスクの基板を剛体で形成するため、回転する光ディスクにおける面ぶれ及びチルトを小さくするために、極めて正確な成形をし、かつ熱変形が生じないように低温で記録膜を成膜しなければならないことから、光ディスク製造に係るタクトタイムが長くなり、コストが上がる原因となる。   In Non-Patent Document 1, since the substrate of the optical disk is formed of a rigid body, the recording film is formed at a low temperature so as to form extremely accurate and to prevent thermal deformation in order to reduce the surface blur and tilt in the rotating optical disk. Since film formation has to be performed, the tact time associated with optical disc production becomes long, which causes an increase in cost.

特許文献１、特許文献２には、安定化部材に対向させて可撓性を有する光ディスクを回転させ、ベルヌーイの法則による空気力学的作用力を利用して光ディスクにおける面ぶれを安定化させる記録再生装置及び可撓性を有する光ディスクの構成が提案されている。   In Patent Document 1 and Patent Document 2, recording / reproduction is performed in which a flexible optical disk is rotated while facing a stabilizing member, and surface blurring in the optical disk is stabilized using aerodynamic action force according to Bernoulli's law. An apparatus and a configuration of a flexible optical disc have been proposed.

特許文献１及び特許文献２では、可撓性を有する光ディスクを安定板上で回転させるため、光ディスクと安定化板とが接して摺動する危険性が高く、ディスク面あるいは安定化板面が傷つくという問題や、摺動により引き起こされる発塵による塵埃などがエラーを発生させる原因となるという問題がある。また、特許文献１及び特許文献２では、単に平面状の安定化板を用いただけであるため、ディスク面ぶれの低減効果に限界があり、高NAの対物レンズを使用する際に、対物レンズとディスクが衝突する危険性は未だ問題として残されたままである。   In Patent Document 1 and Patent Document 2, since a flexible optical disk is rotated on a stabilizing plate, there is a high risk that the optical disk and the stabilizing plate are in contact with each other and the disk surface or the stabilizing plate surface is damaged. There is a problem that dust and the like caused by sliding caused by sliding cause an error. Further, in Patent Document 1 and Patent Document 2, since only a planar stabilization plate is used, there is a limit to the effect of reducing the disc surface shake. When using a high NA objective lens, The risk of disk collisions remains a problem.

非特許文献２には、U-shaped stabilizerなる２つの安定化部材から構成される部材により形成した狭いギャップに、フレシキブルディスクを挟んで回転させることにより、飛躍的に小さなディスク面ぶれに抑える技術が提案されている。   Non-Patent Document 2 discloses a technology that drastically reduces the disc surface shake by rotating a flexible disc with a narrow gap formed by a member composed of two stabilizing members called U-shaped stabilizer. Proposed.

非特許文献２では、フレキシブルディスクと安定化部材との間のギャップが片側25μmと小さいことに加え、安定化部材が１つのディスクの表裏で必ず近接するため、記録再生面をディスクの表裏のいずれに形成した場合にも、安定化部材とディスクとの間にゴミなどを巻き込んで記録再生面を損傷し、直接エラーを引き起こす危険性が避けられない。   In Non-Patent Document 2, since the gap between the flexible disk and the stabilizing member is as small as 25 μm on one side and the stabilizing member is always close to the front and back of one disk, the recording / reproducing surface is placed on either side of the disk. Even in the case of forming the recording medium, there is an unavoidable risk that dust or the like is caught between the stabilizing member and the disk to damage the recording / reproducing surface and directly cause an error.

特許文献３には、光ディスクとの対向面が円弧状をなす円柱状の安定化ガイド部材を用い、光ディスクにおける安定化ガイド部材による空気圧の作用による面ぶれが安定する部位におけるディスク回転方向上流側と下流側とに空気圧の作用を生じさせない領域（安定化ガイド部材がない空間部）を設けて、面ぶれを安定化させた部位の前後位置に光ディスクに逃げとなる部分を存在させ、面ぶれを安定化させた部位での光ディスクにおける反発力を小さくすることにより、空気力による安定化力の効果を増大させる発明が提案されている。   In Patent Document 3, a cylindrical stabilizing guide member having an arc-shaped surface facing the optical disc is used, and an upstream side in the disc rotation direction at a portion where the surface deflection due to the action of air pressure by the stabilizing guide member in the optical disc is stabilized. An area where no air pressure action is generated (a space where there is no stabilizing guide member) is provided on the downstream side, and there is an escape portion on the optical disc at the front and rear positions of the part where the surface shake is stabilized. There has been proposed an invention that increases the effect of stabilizing force by aerodynamic force by reducing the repulsive force in the optical disc at the stabilized portion.

特許文献３では、可撓性光ディスクの面ぶれを確実に抑制することができ、高密度の記録が可能となり、対物レンズとの摺接などの不具合の発生を防ぐことが可能となる反面、実際上において、安定化ガイド部材と記録再生ヘッドとの複雑な位置調整制御が必要となるため、ドライブ制御系の負荷が大きくなるばかりでなく、装置コストがかなり高価なものになる。   In Patent Document 3, it is possible to surely suppress the deflection of the flexible optical disc, to enable high-density recording, and to prevent the occurrence of problems such as sliding contact with the objective lens. In the above, since complicated position adjustment control between the stabilizing guide member and the recording / reproducing head is required, not only the load of the drive control system is increased, but also the apparatus cost is considerably high.

The second stabilizing member 76 and the third stabilizing member 77 are convex in the radial direction, and the surface curvature radius and the width in the disk circumferential direction are continuously changed from the inner circumference to the outer circumference of the disk. The surface curvature radii of the second stabilizing member 76 and the third stabilizing member 77 are 50 mm at a position where the radius is 20 mm and 5 mm at a position where the radius is 60 mm, and continuously change between them. The width in the disk circumferential direction of the second stabilizing member 76 and the third stabilizing member 77 is 12 mm at a radius of 20 mm and 3 mm at a radius of 60 mm, and continuously varies between them.

CASE3では、第４の実施形態の第１走査部５６及び第２走査部５７にかえて設置したレーザ測位計により、第１光ディスク３１及び第２光ディスク３２の中心から半径方向に25mm、40mm、55mmの各位置において、ディスク面ぶれを計測する。計測結果は、図１４の表に示すように、第１光ディスク３１及び第２光ディスク３２ともに、ディスク半径位置25mmにおいてディスク面ぶれ8.0μm、ディスク半径位置40mmにおいてディスク面ぶれ8.0μm、ディスク半径位置55mmにおいてディスク面ぶれ8.0μmである。   In CASE3, a laser positioning meter installed in place of the first scanning unit 56 and the second scanning unit 57 of the fourth embodiment is used in the radial direction from the center of the first optical disc 31 and the second optical disc 32 to 25 mm, 40 mm, and 55 mm. At each position, the disc surface shake is measured. As shown in the table of FIG. 14, the measurement results are as follows. For both the first optical disk 31 and the second optical disk 32, the disk surface blur is 8.0 μm at the disk radius position 25 mm, the disk surface blur is 8.0 μm, and the disk radius position 55 mm. The disc surface shake is 8.0 μm.

比較例では、図１５(a)の平面図及び図１５(b)の断面図に示すように、CASE1と同様に形成した光ディスク８０を、外形直径30mm、内径直径15mm、最終厚み0.3mmのハブ８１に取り付けて15m/secのディスク回転数で回転させ、レーザ測位計８２を半径方向に移動させながら走査するとともに、光ディスク８０を挟んでレーザ測位計８２に対向する位置に、直径10mmの円柱形状の部材の端部表面を曲率100mmに形成した安定化部材８３を近接させるとともに、レーザ測位計に追従して安定化部材８３を移動させる。   In the comparative example, as shown in the plan view of FIG. 15 (a) and the cross-sectional view of FIG. 15 (b), an optical disk 80 formed in the same manner as CASE 1 is a hub having an outer diameter of 30 mm, an inner diameter of 15 mm, and a final thickness of 0.3 mm. It is attached to 81 and rotated at a disk rotational speed of 15 m / sec, scanning while moving the laser positioning device 82 in the radial direction, and a cylindrical shape having a diameter of 10 mm at a position facing the laser positioning device 82 with the optical disk 80 interposed therebetween The stabilizing member 83 having the end surface of the member formed with a curvature of 100 mm is brought close to the member, and the stabilizing member 83 is moved following the laser positioning meter.

比較例では、レーザ測位計により、光ディスク８０の中心から半径方向に25mm、40mm、55mmの各位置において、ディスク面ぶれを計測する。なお、比較例においては、安定化部材８３によりディスク基準面が押し込んまれているため、押し込まれた位置を原点として面ぶれを計測する。計測結果は、図１４の表に示すように、ディスク半径位置25mmにおいてディスク面ぶれ30.0μm、ディスク半径位置40mmにおいてディスク面ぶれ40.0μm、ディスク半径位置55mmにおいてディスク面ぶれ50.0μmである。   In the comparative example, the disc surface shake is measured at each position of 25 mm, 40 mm, and 55 mm in the radial direction from the center of the optical disc 80 by a laser positioning meter. In the comparative example, since the disc reference surface is pushed in by the stabilizing member 83, the surface blur is measured with the pushed position as the origin. As shown in the table of FIG. 14, the measurement results are as follows: the disk surface blur is 30.0 μm at the disk radius position of 25 mm, the disk surface blur is 40.0 μm at the disk radius position of 40 mm, and the disk surface blur is 50.0 μm at the disk radius position of 55 mm.

以上の計測結果から明らかなように、CASE1、CASE2及びCASE3では、比較例に比べて、ディスク面ぶれが小さく抑えられるとともに、ディスク面上の任意半径方向の直線上全域においてディスク面ぶれが小さく抑えられることが明らかである。   As is clear from the above measurement results, in CASE1, CASE2, and CASE3, the disc surface shake is suppressed smaller than in the comparative example, and the disc surface shake is reduced in the entire area on the straight line in the arbitrary radial direction on the disk surface. It is clear that
