Women empowering HDD

New DCA-network

In the "Women empowering HDD" project, a network consisting of six women has been meeting since October 2023 to develop concrete measures to get women more interested in the HDD industry. This includes, for example, a survey that was made available to DCA member companies at the members' meeting with the aim of identifying key figures, the role of women in the companies and any uncertainties.
