Nidec Nagano Technical Center Resumes Operations in New Location

for Industry-leading HDD Motor R&D

Nidec Corporation (“Nidec”, NYSE: NJ) today announced that Nagano Technical Center (“NTC”), one of its Japan-based laboratories engaged in the research and development of spindle motors for  HDDs (Hard Disk Drives), celebrated the start of operation in a new location on May 14, 2009.

Since its original establishment as Nagano Nidec Corporation in 1989, NTC has served to evolve Nidec’s HDD motor technology in Ina County, Nagano. The refreshed NTC, whose construction was completed in Komagane-city in March 2009, is designed to match diversifying demand opportunities and rising technical threshold presented by today’s fast-moving HDD market.  

Situated amid the scenic beauty of the Japan Alpes, the new NTC headquarter laboratory provides the most advanced R&D environments and excellent amenities.

The former headquarter laboratory in Ina has been renamed “NTC Ijima Branch” and is operating as NTC’s reliability assessment division.
