Gebiet der ErfindungField of the invention
Die vorliegende Erfindung bezieht sich im Allgemeinen auf ein hochdichtes optisches Aufzeichnungsmedium. Im Besonderen bezieht sich die vorliegende Erfindung auf ein hochdichtes optisches Aufzeichnungsmedium, das einen Kurzwellenlängen-Laser verwendet, das hochdichte Speicherung und Reproduktion/Wiedergabe der hochdichten Informationsaufzeichnungen ermöglicht.The The present invention generally relates to a high density optical recording medium. In particular, the present invention relates The invention relates to a high-density optical recording medium, the a short wavelength laser used the high-density storage and reproduction / playback the high-density information records allows.
Beschreibung der zugehörigen Technikdescription the associated technology
In den letzten Jahren ist die Entwicklung der optischen Aufzeichnungsmedien, die Laser verwenden, beachtlich gewesen. Ein Beispiel des optischen Aufzeichnungsmediums, wie etwa einer optischen Disc, ist im Allgemeinen derart ausgestaltet, dass ein fokussierter Laserstrahl von ungefähr 1 μm auf eine dünne Aufzeichnungsschicht gestrahlt wird, die auf einem scheibenförmigen Substrat aufgebracht ist, um das Aufzeichnen von Information auszuführen. Das Aufzeichnen ist in einer Weise implementiert, dass unter Absorption der Energie des Laserstrahls der bestrahlte Abschnitt der Aufzeichnungsschicht einer thermischen Deformierung unterliegt, wie etwa Zersetzung, Verdampfung oder Schmelzen. Reproduktion der aufgezeichneten Information wird durch Lesen des Unterschiedes des Reflexionsgrades zwischen dem Abschnitt, der eine durch den Laserstrahl verursachte Deformierung aufweist, und dem Abschnitt ohne diese Deformierung ausgeführt.In recent years, the development of optical recording media, the lasers have been considerable. An example of the optical Recording medium, such as an optical disc, is generally configured such that a focused laser beam of about 1 micron on a thin recording layer is blasted, which is applied to a disc-shaped substrate is to execute the recording of information. The recording is in a way that implements absorption of the energy of the Laser beam, the irradiated portion of the recording layer of a thermal deformation, such as decomposition, evaporation or melting. Reproduction of the recorded information by reading the difference of the reflectance between the Section, which is a deformation caused by the laser beam and the section without this deformation.
Dementsprechend muss ein optisches Aufzeichnungsmedium die Energie des Laserstrahls wirksam absorbieren, und muss auch eine vorbestimmte absorbierte Lichtmenge eines Laserstrahls, das eine für das Aufzeichnen verwendete spezifische Wellenlänge besitzt, und einen hohen Reflexionsgrad für einen Laserstrahl aufweisen, das eine für das Reproduzieren verwendete spezifische Wellenlänge besitzt, um die Reproduktion von Information exakt ausführen zu können.Accordingly An optical recording medium needs the energy of the laser beam absorb effectively, and must also absorb a predetermined amount Amount of light of a laser beam using one used for recording specific wavelength has, and have a high reflectivity for a laser beam, the one for the reproducing used has specific wavelength to reproduce to execute information exactly to be able to.
Jedoch ist die Speicherkapazität des optischen Aufzeichnungsmediums, das die Laserquelle verwendet, aufgrund von optischer Diffraktion eingeschränkt. Derzeit werden einige Prinzipien und Verfahren zur Erhöhung der Speicherdichte der optischen Informationsspeichermedien diskutiert, einschließlich solcher wie etwa Verschieben der Wellenlänge der Laserquelle, zum Beispiel, von einem roten Laser zu einem blauen Laser, oder Erhöhung der objektiven numerischen Apertur („NA") der optischen Linse. Einige weitere Verfahren schließen Verbesserung der Codierverfahren des digitalen Signals ein, oder ein Discspeicherverfahren durch Verwenden einer extrafeinen Auflösung nahe der optischen Feldstruktur, oder eine Technologie, um die Speicherkapazität des Informationsspeichermediums (z.B. eine Compact Disc) durch Verwenden von mehreren übereinander liegenden Aufzeichnungsschichten zu erhöhen, d.h. die Aufzeichnungsschichten der Informationsspeichermedien sind in eine dreidimensionale Raumstruktur mit mehreren Schichten eingebracht, um die Speicherkapazität zu erhöhen. Sämtliche oben beschriebene Verfahren können angewendet werden, um die Speicherkapazität des optischen Aufzeichnungsmediums wirksam zu erhöhen.however is the storage capacity the optical recording medium using the laser source, restricted due to optical diffraction. Currently some are Principles and methods of increase the storage density of the optical information storage media is discussed, including such as shifting the wavelength of the laser source, for example, from a red laser to a blue laser, or increase the objective numerical aperture ("NA") of the optical lens Close the procedure Improvement of the coding method of the digital signal on, or suggest a disk storage method by using extra fine resolution the optical field structure, or a technology, the storage capacity of the information storage medium (e.g., a compact disc) by using multiple ones to increase lying recording layers, i. the recording layers The information storage media are in a three-dimensional space structure introduced with several layers to increase the storage capacity.
