After describing the configuration of the optical flying head, the readout signals and tolerances are presented. The C/N (carrier to noise) ratio was 49.53 dB for 0.2 gm of the mark length. The tolerances of relative tilt and decenter were /spl plusmn/1deg and /spl plusmn/100 gm, respectively. We think a more practical head structure can be realized by miniaturizing the condensing optics on the flying head.","PeriodicalId":393728,"journal":{"name":"International Symposium on Optical Memory and Optical Data Storage Topical Meeting","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122268633","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}

Two element objective lenses with NA 0.85 have been developed and tried for next generation optical disc systems. However, we are sure that a single lens is required which would help to achieve a longer working distance and a smaller diameter because the size and the cost will be major factors in the future of NA 0.85 lenses. Last year we produced a prototype single lens with NA 0.85. Here we introduce the design concept, and also report on the favorable performance of the new lens re-designed for mass production.","PeriodicalId":393728,"journal":{"name":"International Symposium on Optical Memory and Optical Data Storage Topical Meeting","volume":"23 257","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131692010","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}

Chong et al, Jpn. J. Appl. Phys. vol. 39, p. 737, 2000, and J. Appl. Phys. vol. 91, 2002). This technology paves an alternative way to develop phase change materials for optical disks. On the other hand, with the development of DVD technology, DVD recording is being introduced in two different markets simultaneously, i.e., the DVD video recorder and the DVD writer for personal computer use. It is expected that the recording speed of rewritable DVD media should be like the rewritable CD, which is compatible with CD writers with different speeds. Therefore, it is necessary to develop rewritable DVD media to cover a broad range of recording speeds in order to make them compatible with different DVD recorders and drives. In this contribution, we present recent progress on the recording properties of the SLL disk at different recording speeds by tuning the stack structure, aiming to make the SLL disk multispeed compatible.","PeriodicalId":393728,"journal":{"name":"International Symposium on Optical Memory and Optical Data Storage Topical Meeting","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115619957","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}

Neither technique can generate both ultra-small spot size and exhibit high optical efficiency. Small spot size produces higher contrast signals, which leads to an increase in signal-to-noise ratio (SNR) and an enlargement in the capacity of an optical disk. Higher optical efficiency gives higher throughput in the optical system, which accelerates data rate. The technique of near-field Aperture SIL (APSIL), which combines a dielectric aperture probe and a SIL, is a promising method to achieve both small spot size and high optical efficiency. The objective of this paper is to explore the writing conditions for implementing APSIL to reduce mark size to a fraction of that from the far-field data storage systems. In this paper, we investigate the effect of polarization of the light on the spot profile and the optimal axial focus position by experiments and simulations.","PeriodicalId":393728,"journal":{"name":"International Symposium on Optical Memory and Optical Data Storage Topical Meeting","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124605021","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}

One of the problems with these approaches is that an error in the cover-layer thickness of only a few microns can lead to serious spherical aberration. (SA). This is a particularly serious problem in dual-layered discs due to the distance between the two recording layers. Another problem is the narrow working distance (WD) of the two-element objective lens, which can result in the lens crashing onto the disc. To overcome these problems, we previously described accurate detection of and dynamic compensation for SA (Jpn. J. Appl. Phys., 40, 2001, and Proc. of SPIE, 4342, 2002) and a single-element high NA objective with a wide WD (Tech. Dig. of ISOM, 2001).
