Seagate and Toshiba vie to buy TDK’s magnetic‑head unit in a multi‑billion‑dollar deal
Seagate Technology and Toshiba are competing to acquire TDK’s magnetic‑head business, the sole independent supplier of HDD recording heads. The negotiations began in spring 2026 with Toshiba and escalated in summer when Seagate submitted a higher offer. The potential transaction is described as being worth several billion dollars and would require antitrust clearance.
Why it matters
Goldman Sachs notes that a sale could reshape HDD supply chains and trigger regulatory scrutiny, potentially affecting pricing and capacity for Seagate, Toshiba and Western Digital. The outcome may also provide TDK with capital to expand its battery and sensor businesses.
