The direction where Hand Disk Drive business goes - How much high will the density of HDD? -

[2009, Feb. 25]

1. Introduction

On February 17, Fujitsu announced that it carried out basic agreement by transferring hard disk (HDD) business to Toshiba. Fujitsu transfers the hard disk drive business except HDD head and media business to Toshiba. Although high-densitization of information record is conventionally called for from the hard disks, the limit has been nearing high densityization by extension of the conventional technology. Therefore, in addition to the technology development on high-density recording and playback HEAD, the technical development about patterned media is being activated in recent years. Here, the situation of the technical development about patterned media was analyzed.
XLUS was used based on these, concept search was performed, using the patent relevant to patterned media two or more, and about 300 patents exhibited in 2008 considered to relate to patterned media were extracted. As the major player relevant to patterned media Hitachi besides above-mentioned FUJITSU and Toshiba, TDK, Fuji Film, Canon, Panasonic, Showa Denko, Fuji Electric, Advanced technology (affiliated companies of Fuji Electric), etc. are mentioned. Any company is performing technical development about manufacture of a medium, as long as current patent applications are looked. When technology development is performed, it begins from development of elemental technologies for realizing a function (in the case of patterned media production method of a media etc.), and system technology development (the head for utilizing a media, a reading algorithm, circumference circuitry, etc.) required for utilization progresses. Since the technology development concerning the technology development of each company medium manufacture is a subject, present is a development phase of the component engineering, and is expected that the technology development towards practical use will harsh from now on.
