The whole testing system is controlled by a computer. The laser power, pulse duration time and external applied magnetic field can be adjusted in a wide range. The focused spot size is less than 1 micrometers on the recording layer which allows high laser power irradiation, up to 30 mW. This testing system can evaluate the writing and erasing characteristics of phase-changes and magneto-optical disks. The design idea and experimental results of this testing system are presented.","PeriodicalId":212484,"journal":{"name":"Optical Storage and Information Data Storage","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123843237","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}

The results show that the stability of three dyes with molecular structure of heterocyclic stem nuclei against photooxidation is in such order: benzoxazole > benzothiazole > benselenazole. It was found through quenching experiments that the photooxidation of cyanine dyes not only relates to the singlet oxygen but also to the superoxide anoin, however single oxygen plays a dominant role. We have succeeded in drastically improving the photostability of three cyanine dyes by using a dithiol nickel chelate as a singlet oxygen quencher.","PeriodicalId":212484,"journal":{"name":"Optical Storage and Information Data Storage","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130114948","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}

The optical storage characterizations of GeSb2Te4 thin film demonstrate clearly that larger reflectivity contrast can be obtained at lower power Argon laser (514.5 nm) irradiation. The erasing contrast is relatively lower but can be improved by multi-layer films match.","PeriodicalId":212484,"journal":{"name":"Optical Storage and Information Data Storage","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125502033","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}
