TIPS for Member・ Reduce development redundancy・ Activation of HDD business

Set CompanyReduce evaluation on each sightEasy negotiation about drive specEasy select of HDD 　

Device Company　 Standardize Device Reduce R&D redundancyGet early stage requirement information

　 Tester Company New business for new testing method

　 Drive Company　 Focus development target Standardize device Reduce material cost
