A tonearm unit includes: an arm member having a tip to which a cartridge is attached; and a raising and lowering mechanism which raises and lowers the arm member with respect to a phonograph record along an axis. The raising and lowering mechanism includes: a cam base supporting the arm member; a ring cam provided to be rotatable about the axis with respect to the cam base; a first guide portion on the cam base, extending at an angle along a rotation direction of the ring cam; and a second guide portion on the ring cam, extending at an angle along the rotation direction so as to face the first guide portion. When the ring cam rotates with respect to the cam base, the cam base is raised and lowered with respect to the ring cam as a result of the second guide portion sliding along the first guide portion.

In at least one embodiment, a record or vinyl playback device includes a spindle clamp at a central region of the playback device and a peripheral clamp at a peripheral region of the playback device. In operation, the spindle clamp is inserted into an opening at a center of a record to be played utilizing the playback device. Once the record is present on the playback device, the spindle clamp is actuated to mechanically engage one or more spindle clamp arms with a central region or surface of the record, and the peripheral clamp is actuated to mechanically engage one or more clamp structures with a peripheral region or surface of the record. The spindle clamp arms may rotate inward and outward from a shaft of the spindle clamp, and the clamp structures may translate inward and outward from a center of the record.
