Method for writing and reading data on a multi-layer recordable interferometric optical disc and method for fabricating such

A recordable compact disc comprises a 0.6 millimeter clear plastic or glass substrate on which is grown a thin-film image layer having several distinct recording planes. Each recording plane is separated from the next by a clear plastic layer. Each recording plane includes an organic dye layer in combination with another clear layer that has a different index of refraction. Different color dyes are used for each recording plane. A method for storing and reading data to and from a multilayer recordable compact disc with different color dye layers uses high powered color lasers to write each recording plane and low powered monochromatic reading lasers that are sensitive to the constructive and destructive light interference effects caused by micron variations in the clear plastic layers in each recording plane. The micron variations used for each recording plane are unique and chosen along with the monochromatic reading laser colors to have minimal crosstalk between recording-plane data channels.

Method and device for recording data onto recording medium

FIELD: physics, computer engineering. ^ SUBSTANCE: recording medium has an initial region, a final region and a data area, where the data area has a user data region and a back-up region. When a microcontroller receives an instruction for physical recording first data into the first region in the user data region and determines that the first region is included in the pre-recorded region, it controls the recording device to record first data into the first overriding region instead and temporarily store the first data record in the memory of the recording device. The first data record specifies the location of the first region and the first overriding region. If the microcontroller detects that the first overriding region is defective, it controls the optical recording device to record first data into the second overriding region and temporarily store a second data record in the memory of the recording device. The second data record specifies the location of the first and second overriding regions. Data record specifying location of the first region and the second overriding region is stored in the disc temporary control region. ^ EFFECT: reduced input of data records. ^ 17 cl, 10 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 384 897 (13) C2 (51) МПК G11B 7/00 (2006.01) G11B 20/18 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2007102586/28, 12.08.2005 (24) Дата начала отсчета срока действия патента: 12.08.2005 (73) Патентообладатель(и): ЭлДжи ЭЛЕКТРОНИКС ИНК.

Apparatus for reproducing a disk

종래 CD-ROM 드라이브에 있어서는 CLV 방식의 고속재생을 실현하는 경우의 디스크 모터의 고성능화가 장치의 소형·경량화 및 저비용화를 실현함에 장해가 되었다. In the conventional CD-ROM drive, the high performance of the disc motor in the case of realizing the high speed reproduction of the CLV method has hindered the realization of the small size, the light weight and the low cost of the device. 본 발명은 CLV 디스크 상의 데이타 영역을 임의의 트랙 위치를 경계로 그 트랙 위치를 포함하는 내주부와 외주부로 미리 구분해 놓고, 디스크 외주부로부터의 신호 독출은 CLV 방식으로 행하고, 디스크 내주부로부터의 신호 독출은 상기 임의 트랙 위치를 CLV 재생하는 때의 회전수로 고정해 CAV 방식으로 행하는 것을 특징으로 한다. CLV 재생시에 디스크 모터의 회전수가 높아지는 디스크 내주부의 재생을 CAV 방식으로 행함으로써, 디스크 모터의 최고 회전수를 저감할 수 있으며, 디스크 모터의 부담 및 진동 문제를 경감시킬 수 있다. The present invention divides the data area on the CLV disc into an inner circumferential portion and an outer circumferential portion including the track position in advance at an arbitrary track position, and reads signals from the outer circumferential portion of the disc in a CLV manner, and signals from the inner circumference of the disc. The reading is performed by the CAV method by fixing the arbitrary track position at the rotational speed at the time of CLV reproduction. By reproducing the inner circumferential portion of the disk, which increases the rotational speed of the disk motor at the time of CLV reproduction, by using the CAV method, the maximum rotational speed of the disk motor can be reduced, and the burden and vibration problems of the disk motor can be reduced.
