The authors first indicated the analitycal model for air bearing dynamics of dual structure mother ship slider mechanisms, and the advantages of this mechanisms were discussed from the dynamics points of view, compared with conventional flying head slider mechanisms. Furthermore, the effects of stiffness and damping characteristics of an integrated microsuspension mechanism on mother ship slider system dynamics were also analyzed numerically. Considering those numerical simulation results, optimum design method for microsuspension gimbals was established to suppress the coupled vibration between primary and secondary sliders, caused by secondary slider’s piggy-backed structure. It became clear that micromachined integrated microsuspension mechanisms have to be designed not only from the static and silicon micromachined process points of view, but also from the mother ship slider dynamics points of view, in order to achieve head/disk interface reliability in high density proximity magnetic recording.","PeriodicalId":414918,"journal":{"name":"9th International Symposium on Information Storage and Processing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129450612","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 extended operator formulation (Parker, 1997) is exploited to discretize the system using Galerkin’s method. The coupled vibration modes of the system consist of disk modes, in which the disk dominates the system deformation, and spindle modes, in which the spindle dominates the system deformation. Both the natural frequencies and vibration modes are strongly affected by disk flexibility. If the membrane stresses associated with disk rotation are neglected then the system exhibits flutter instabilities, but these instabilities are not present when membrane stresses are included. Natural frequency veering between disk and spindle frequencies is prominent at low speeds and substantially affects the spectrum and stability. No veering is observed at high speeds where rotational stress stiffening diminishes disk-spindle coupling and causes the natural frequencies to converge to those of a rotating spindle carrying a rigid disk. Changes to the vibration modes are examined in terms of a strain energy ratio measuring the contribution of the disk strain energy to the total modal strain energy.","PeriodicalId":414918,"journal":{"name":"9th International Symposium on Information Storage and Processing Systems","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115652026","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}
