The most applicable field in optical storage is used as write-once media, such as recordable compact disk (CD-R). It is of great interest to explore new organic compounds, which can perform rewritable storage. It is well known that the photochromic organic compounds are always heat and light unstable. The phthalocyanine compounds have received considerable attention because of their good thermal and chemical stability which ensure a long storage life. We have reported the write-once performances and reversible optical property change of phthalocyanine thim films(1,2). In this paper the reversible phase chane and rewritable performances are presented.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"256 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":"123096066","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}

So far, magneto-optical-mode storage on a Co/Pt film [1] and optical-mode one on the LB film of amphiphilic azobenzene derivative [2] have been reported. Recently, with regard to the latter technique, much smaller pit sizes are successfully achieved by using a nanometric aperture. In order to increase the write speed, high excitation density through the aperture is required. For this purpose, we optimize the shape of fiber probe for attaining high transmission efficiency of light. Its ability in the application to nano-photonic devices is also demonstrated through the spatially resolved spectroscopy of novel-structured semiconductor devices.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"59 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":"133955280","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}

Optical disk drives have interactions between these servo loops attendant to the characteristics of actuators and the error signal sensing schemes employed. Simple actuators and error signal sensing methods are desirable to reduce the manufacturing costs; however, large interactions, if present may degrade the servo performance. This can result in a degradation in the error rejection ratio, seek time, and seek reliability.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"24 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":"134201363","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}

We expect a fully backward-compatible erasable CD (CD-E) adds more attractive applications on CD-ROM world. In the CD-E, two important specifications in the CD Standard has to be conformed; high reflectivity of greater than 70% and large signal modulation of greater than 60%. The feasibility of the CD-E has been demonstrated2) using Ge-Te-Se phase-change material in a five-layer MIPIM structure, in which M, I and P denote metallic mirror, interference and phase-change layer, respectively. In the past study, full backward-compatible CD-E was achieved, however it required high laser power for writing, which is approximately 60mW on the disk, and less overwrite cyclability of 10 times. Our final goal in this study is to develop a practicable CD-E which has high performances in writing sensitivity and overwrite cyclability.","PeriodicalId":322309,"journal":{"name":"Joint International Symposium on Optical Memory and Optical Data Storage","volume":"66 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":"121711170","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}
