The Nagano Technical Center is not limited to the development of spindle motors for HDDs.
He is also responsible for the production of prototypes, production line automation, process improvement, etc.
Function and function
Together with the Central Research Institute of Development Technology, the Nagano R&D Center is responsible for the research and development of HDD spindle motors for HDDs, which are the backbone products of Japan Denco (Nidec). HDD, as the protagonist of computer recording media, has a broader market in the era of big data, and is still increasing the recording density at a rate of 30-40% per year. HDD spindle motors are the core functions of HDDs as hard disk drive devices, and Japan Denco (Nidec) has a global market share of 80% in the HDD spindle motor market. In particular, the Nagano R&D Center is engaged not only in the development and design of products, but also in the production of prototypes, support for the start-up of mass production, automation of production lines, process improvement and systematization of efficiency. The spindle motor for HDDs developed by the Nagano R&D Center has been mass-produced at various plants in Thailand, the Philippines, and China.
Products & Results
Spindle motor for HDD
The Nagano Technical Center and the Central R&D Center have jointly developed the world's first 7 mm thick spindle motor for HDDs that can be installed in ultrabooks and tablets, and are developing new products ahead of their competitors. In addition, as thinning HDDs are required to have semiconductor-level dimensional accuracy and a clean environment, the Nagano Technical Center is further developing the experimental environment and various analytical equipment and laboratory equipment required in the fields of picogram and nanometers, including trace element analyzers.
Equipment & Experimental Setup
No sound room
In order to measure sound, which is one of the most important factors in the evaluation of product characteristics, a dedicated measurement room has been set up.
Cleanroom
There are rooms of various sizes according to different purposes. In terms of cleanliness, the main cleanroom has ISO Class 5 or higher, and each cleanroom has made great efforts to maintain cleanliness.
Production Technology Laboratory
We are committed to research on the efficiency and automation of production line equipment in the mass production stage.
Gas chromatography analyzer
A gas chromatography analyzer capable of performing mass analysis with a picogram:pg (minus 12 square of 10) grade with 100 times higher accuracy than conventional products.
Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS)
Time-of-flight secondary ion mass spectrometry (TOF_SIMS) is used to analyze which components (atoms, molecules) are present on the surface of a solid sample. It can detect very small amounts of components at the ppm level, and is suitable for the detection of organic and inorganic substances.
Laser Raman spectrometer
Laser Raman spectrometers enable three-dimensional measurement of the chemical state of substances in the sub-micro-nano domain
Receiving inspection room
Receiving inspection of parts and materials used in prototype assembly. We can measure sub-micron dimensions and fine shapes, and we strive to eliminate measurement differences between suppliers and production plants while meeting customer needs.
