  • Patent number: 4017898
    Abstract: The apparatus includes a transducer carrying frame having a spine and arms extending from the spine. A transducer is mounted at the foot of the spine and two sled bearings are mounted at the outer ends of the arms, to form a sled assembly which can slide over the recording surface of a magnetic recording disc with the contact face of the transducer and the bearing faces of the sled bearings contacting the recording surface. The sled assembly is attached to the outer, non-supported end of a cantilever leaf spring. When this cantilever leaf spring is undeflected it holds the sled assembly near the recording surface of the recording disc but out of contact with it. A presser foot is provided to press upon the sled assembly and thus deflect the first cantilever leaf spring and bring the sled assembly into recording and reproducing contact with the recording surface of the recording disc. The presser foot is mounted on a second cantilever leaf spring.
