Magnetic printing technology-application to HDD
IEEE Transactions on Magnetics, 2003As the recording density of hard disk drives is being rapidly increased, the current servo track writing method using a conventional servo track writer has become more costly and technically difficult. In order to solve the problem, the authors propose a new magnetic contact duplication technology using a lithographically patterned master disk and ...

A single chip HDD PRML channel
Proceedings of Custom Integrated Circuits Conference, 2002A PRML (Partial Response Maximum Likelihood) channel chip employing a mixed-signal 0.8 /spl mu/m BiCMOS process for hard disk drive (HDD) applications is described. This chip performs the complete write, read, and servo functions using only five external components with a data rate of up to 120 Mb/sec.

Cloud storage application area of HDD–SSD hybrid storage, distributed storage, and HDD storage
IEEJ Transactions on Electrical and Electronic Engineering, 2016For a typical IaaS (infrastructure as a service) cloud usage, to strengthen a system, temporary and frequent provisioning of virtual volumes is needed. However, the performance of HDD (hard disk drive) storage is not sufficient and has become a bottleneck in IaaS cloud now.

RRO/NRRO characteristics in mobile HDDs
2009 Asia-Pacific Magnetic Recording Conference, 2009The characteristics of repeatable runout (RRO) and non-repeatable runout (NRRO) of HDDs have to be clarified for higher tracks per inch since the static positional accuracy has almost reached its limit. The most dominant component in NRRO and even in RRO is torque disturbance.

Use case study of HDD-SSD hybrid storage, distributed storage and HDD storage on OpenStack
Proceedings of the 19th International Database Engineering & Applications Symposium on - IDEAS '15, 2014For typical IaaS cloud usage, frequent provisioning of virtual volumes is needed. However, performance of HDD storage is not sufficient and becomes bottleneck in IaaS cloud. In this paper, we studied a comparison of HDD-SSD hybrid storage, distributed storage and normal HDD storage as block storage of OpenStack Cinder and evaluated applicability of ...
