OHSAWA Yuichi
Toshiba has developed a fundamental technology for read heads for hard disk drives having a recording density in the terabit per square inch (Tbpsi) class. The new technology is based on the magnetoresistance (MR) phenomenon through magnetic nanocontacts manufactured by our original fabrication process and our original MR measurement methods. An MR ratio as large as approximately 140% was successfully achieved by a test element formed in sputtered nickel-iron (NiFe) thin film at room temperature.
By applying this technology to actual read heads, it will be possible to improve the data transfer rate and power consumption compared with tunneling MR heads using a magnesium oxide (MgO) barrier, which are currently being developed as next-generation read heads.

UCHINO Masashi / FUNAKI Ryoichi / ENDO Takahisa
With the remarkable progress of their performance and functionality, PCs are now used in various situations including the business world. However, there are numerous security risks in terms of managing the hardware, software, and data on PCs. Thin client systems for mobile computing have a limitation in that the mobility of the client devices degrades performance and functionality. There is a need to create a safe client environment without compromising the capabilities of the PCs.
Toshiba Solutions Corporation has developed FlexClientTM, a new client security system that makes best use of standard PCs in and out of the office. When the PCs are connected to a LAN in the office, FlexClientTM makes them boot from the network using a centralized, Internet Small Computer System Interface (iSCSI)-based storage and prevents the PCs from storing data on the internal disk drive. When the PCs are offline in a mobile environment, it provides a secure way of using the internal disk drive. Data on the disk are managed from the server. We have deployed FlexClientTM in our systems, allowing us to manage security risks in an Information Security Management System (ISMS)-compliant business environment.
