Hitachi Ltd. and International Business Machines Corp. on Tuesday announced an agreement to integrate their hard disk drive businesses under a joint company to be majority-owned by Hitachi.

The deal follows an agreement between the two companies announced on April 17 to form a strategic alliance in storage technologies and to set up a joint venture to integrate their HDD operations.

The joint company will be headquartered in San Jose, Calif., and managed by an independent team comprising executives from Hitachi and IBM's HDD operations, they said.
