【課題】 光ディスク記録面からのレーザー光乱反射の問題を光ピックアップ側で解決し、光ディスクの音質・画質を向上することを目的とする。
【解決手段】 この発明の光ディスク記録再生装置は、光ディスクからのレーザー光乱反射による不要なノイズ信号を抑制し且つ記録再生に必要なレーザー光に影響を与えない為、光を吸収する表面仕上げをした円形又はスリット状の有孔遮蔽板を、光ピックアップメカとは機構的に独立させて取付け、且つトレイ式光ディスク記録再生装置に於いてはシャーシ及びサブシャーシ等に新たに清掃口を設け、既成のカメラ用レンズクリーナーによる清掃を可能にしたことを特徴とする。
【選択図】図11PROBLEM TO BE SOLVED To improve the sound quality and image quality of an optical disc by solving the problem of irregular reflection of laser light from the optical disc recording surface on the optical pickup side.
The optical disk recording / reproducing apparatus of the present invention has a surface finish that absorbs light in order to suppress unnecessary noise signals due to irregular reflection of laser light from the optical disk and not to affect the laser light necessary for recording / reproducing. A circular or slit-shaped perforated shielding plate is attached mechanically independent of the optical pickup mechanism, and in the tray type optical disk recording / reproducing device, a new cleaning port is provided in the chassis and sub-chassis. It can be cleaned with a camera lens cleaner.

Description
この考案はCD再生機、SACD再生機、DVDオーディオ再生機、MD記録再生機、CD−R/RW、DVD再生機、DVD−RAM、DVD−R/RWに関する考案です。 This device is about CD player, SACD player, DVD audio player, MD recording / reproducing device, CD-R / RW, DVD player, DVD-RAM, DVD-R / RW.
光ディスクは耐久性に優れているが、光ピックアップのセンサーがディスクの記録面に対して無接触であるがゆえに、光ディスク記録面からのレーザー光乱反射が、音質・画質に与える影響が取沙汰され、光ディスクのエッジ処理による改善方法が考案されたが、装置が高額であり、ディスクの記録面にキズを付ける可能性もあり一般的ではない。 Although the optical disc is excellent in durability, the influence of the laser light irregular reflection from the optical disc recording surface on the sound quality and image quality has been investigated because the sensor of the optical pickup is non-contact with the recording surface of the disc. Although an improvement method by edge processing of an optical disk has been devised, the apparatus is expensive, and there is a possibility of scratching the recording surface of the disk, which is not general.
この考案は光ディスク記録面から発生するレーザー光乱反射の問題を、光ピックアップ側で解決することを目的とする。 An object of the present invention is to solve the problem of irregular reflection of laser light generated from an optical disk recording surface on the optical pickup side.
この発明の光ディスク記録再生装置は、光ディスクからのレーザー光乱反射による不要なノイズ信号を抑制し且つ記録再生に必要なレーザー光に影響を与えない為、光を吸収する表面仕上げをした円形又はスリット状の有孔遮蔽板を、光ピックアップメカとは機構的に独立させて取付けたことにより音質・画質が向上した半面、クリーニングディスクによるレンズ清掃が不可能となったので、トレイ式光ディスク記録再生装置に於いてはシャーシ及びサブシャーシ等に新たに清掃口を設け、既成のカメラ用レンズクリーナーによる清掃を可能にしたことを特徴とする。 The optical disk recording / reproducing apparatus according to the present invention suppresses unnecessary noise signals due to irregular reflection of laser light from the optical disk and does not affect the laser light necessary for recording / reproduction, so that it has a circular or slit shape with a surface finish that absorbs light. The perforated shield plate is mounted mechanically independent of the optical pickup mechanism, but the sound quality and image quality are improved, but the lens cannot be cleaned with a cleaning disk. In this case, a new cleaning port is provided in the chassis, sub-chassis, etc., and cleaning with an existing camera lens cleaner is possible.
この発明の光ピックアップは光ディスクからの乱反射によるノイズ信号を、音声・映像の記録再生に必要な最小限の径に明けられた孔を有する遮蔽板によって抑制する効果があり、クリアな音質のCD再生機、SACD再生機、DVDオーディオ再生機、MD録音/再生機、CD−R/RW、クリアな音質・画質のDVD再生機、DVD−RAM、DVD−R/RWを製作することができる。 The optical pickup according to the present invention has an effect of suppressing a noise signal due to irregular reflection from an optical disk by a shielding plate having a hole opened to a minimum diameter necessary for recording and reproduction of audio and video, and reproducing a CD with a clear sound quality. Machine, SACD player, DVD audio player, MD recorder / player, CD-R / RW, DVD player with clear sound quality / image quality, DVD-RAM, DVD-R / RW.
考案を最も簡単に実施するには、既存のCD及びDVD再生機等の光ピックアップに、円形又はスリット状の有孔遮蔽板を両面テープで貼ることで可能となる。孔の形状を円形かスリット状にするかは、有孔遮蔽板を光ピックアップケーシングに直接取り付けられるかどうかで決まる。遮蔽板の孔の大きさは記録再生に影響を与えない条件で、出来る限り小さな形状で作ることが肝要である。
マスプロの対象とするならば、両面テープを使って有孔遮蔽板を固定するのではなく、螺子の使用が品質管理上望ましい。
有孔遮蔽板を改造用の単体部品として製作し、既成の光ディスク記録再生装置へも適用可能とする。
トレイ式光ディスク記録再生装置の場合、通常光ピックアップの汚れはクリーニングディスクで除去するが、光ピックアップに有孔遮蔽板を貼るとこの方法が使用出来なくなるので、この問題はシャーシ及びサブシャーシに対物レンズ清掃口を明け、カメラ用のレンズクリーナーで埃を吹き飛ばすことで解決出来る。The simplest implementation is possible by attaching a circular or slit-shaped perforated shielding plate with double-sided tape to an existing optical pickup such as a CD and DVD player. Whether the shape of the hole is circular or slit depends on whether the perforated shielding plate can be directly attached to the optical pickup casing. It is important that the size of the hole in the shielding plate be as small as possible under conditions that do not affect recording and reproduction.
For mass production, it is desirable to use screws instead of fixing the perforated shielding plate using double-sided tape.
A perforated shielding plate is manufactured as a single component for remodeling and can be applied to an existing optical disc recording / reproducing apparatus.
In the case of a tray-type optical disk recording / reproducing device, dirt on the optical pickup is usually removed with a cleaning disk, but this method cannot be used if a perforated shielding plate is attached to the optical pickup. This can be solved by opening the cleaning port and blowing off dust with a lens cleaner for the camera.

AV機器の性能を上げることは、一般家庭への機器の購買層を広げ且つ低迷しているディスクの拡販にも繋がる。
又この改善効果は放送局やレコーディングスタジオ等にも波及することで、音楽文化にも貢献できるものである。Increasing the performance of AV equipment will lead to an increase in the purchasing range of equipment for general households and sales expansion of sluggish disks.
This improvement effect can also contribute to music culture by spreading to broadcasting stations and recording studios.
