The purpose of such R&D work is to implement compact and light-weight pickup heads with a rigid structure, to enable economical mass production by the planar fabrication technique, and to exploit novel functions and improved performances offered by the use of guided-wave optics. In this paper, I would like to review the current status of the integrated-optic technology for data storage with emphasis on the author's work, and discuss the possibilities, problems and subjects for future work.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124829062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the beginning of developing a high density optical disc applicable to a DVD, basic factors of an optical disc are reconsidered free from accepted idea to prove the ideal figure. First of all disc thickness was reconsidered and optimized to choose 0.6 mm1). That is because a higher NA objective lens can be used without increasing of aberration caused by disc tilt. A high efficiency data format suitable for 0.6 mm discs has been also developed. As the result a DVD having 5 GB of user capacity in CD size has been achieved. This DVD can contains more than 140 minutes of video signal with the same quality as the conventional analogue video discs.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122362167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two optical recording methods i.e. (1) optical modulation recording and (2) magnetic field modulation recording. The optical modulation recording has more like optical oriented features to modulate laser beam with data while DC magnetic field is applied. The recorded mark size are limited by the diffraction optical spot size λ/2NA and complex media are necessary to comply with the demand of direct over writing. The magnetic field modulation recording method on the other hand has more magnetic oriented features to modulate magnetic field with data while constant waveform (DC or pulse train) laser irradiation is applied. The recorded mark size are limited by the magnetic field response applied and not limited by the optical spot size. The DC laser irradiation type has been used at Mini Disk™ and Laser pumped type has been used at HS ™ 3.5inch 650MB capacity magneto-optical drive. Moreover complex media are not necessary to comply with the demand of direct over writing, therefore the media applied magnetically induced super resolution(MSR) can be used easily.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114383716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, considerable improvements to both disc capacity and transfer rate can be realized by its implementation. Unlike many methods that improve disc capacity, PDM has the advantage of increasing data transfer speed in direct proportion to obtained increases in data capacity. It is also compatible with other innovations under development, including smaller pits read by shorter wavelength lasers and higher NA lenses, faster disc spin-rates, and double-sided, dual depth or multilayer discs. Performance improvements from PDM are additional to those achieved from other innovations.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130623199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A quadri-valued MO media has been realized using a magnetic field modulation method. For actual application of the media, it is necessary to increase the data transfer rate and recording density. The purpose of this study is producing a quadri-valued MO media which can record with a very small switching field less than 200 Oe, which is similar field strength with an conventional MO drive. On such a media, the quadri-valued recording is available without a drastic change of the drive design. The media has twice a large data transfer rate and linear bit density than those of a conventional MO media.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130280115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
