Glassbridge Enterprises, known as Imation Corporation prior to 2017, is an American holding company. Through the company's two subsidiaries, Glassbridge focuses primarily on investment, asset management and global enterprise data storage. Prior to the name change, Glassbridge had three core elements – traditional storage (magnetic tape and optical products), secure and scalable storage (data backup, data archive and data security for small and medium businesses) and what the company calls “audio and video information” products.
Imation was started in 1996, when 3M spun off its data storage business. The company underwent a divestment of non-core businesses, and invested in four core product technology areas: secure storage, scalable storage, wireless/connectivity, and magnetic tape.
As part of 3M, the company was involved in the development of many technological improvements in data storage, such as the introduction of the first magnetic tape in 1947, the first quarter-inch tape cartridge for data storage (QIC) in 1971, and the 3.5-inch (89 mm) floppy disk in 1984.
In February 2012, Imation announced a product set for securing mobile data, identities, and workspaces, based on the premise that employees used portable storage devices to transport corporate data.
The security news followed five acquisitions the company made in 2011 in scalable storage and data security: ENCRYPTX; MXI Security from Memory Experts International; the assets of ProStor; the secure data storage hardware business of IronKey; and intellectual property from Nine Technologies. Imation received an exclusive license from IronKey for its secure storage management software and service and a license to use the IronKey brand for secure storage products.
In October 2011, Imation products for small and medium businesses centered on its DataGuard and InfiniVault multi-tier data protection and data archive appliances.
The company sold consumer electronics, headphones and accessories under the Imation, Memorex, TDK Life on Record, and XtremeMac brands. The combined Imation, Memorex and TDK Life on Record brands made the company into a global market share leader in sales of CD-R and DVD media before that business was shut down in 2016.
Imation changed its name to Glassbridge Enterprises on February 21, 2017.
