The optical disc drive may comprise a spindle hub coupled to an optical assembly. The optical disc drive may further include a disc clamp assembly configured to hold an optical disc on the spindle hub, the disc clamp assembly including a hub clamp partially comprised within a clamp carriage. The hub clamp of the optical disc drive may be biasedly drawn toward the spindle hub when in a first position and biasedly drawn toward the clamp carriage when in a second position. The bias may be generated by at least one ferromagnetic material integrated into the hub clamp and at least one ferromagnetic material integrated into the spindle hub."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive retraction of a hub clamp in an optical disc drive","description":"Embodiments for passive retraction of a hub clamp in an optical disc drive.
