Abstract

An apparatus for locking a rotatable portion of a storage device is provided. The apparatus comprises a component irrotatably engaged with the rotatable portion, the component having first teeth for engaging second teeth disposed on a surface irrotatable with respect to the component. A spring is disposed between the component and the reel to urge engagement of the first teeth and the second teeth. The component is slidably engaged with the reel such that by pulling on the component, the component slides with respect to the reel and the first teeth disengage from the second teeth, thereby permitting the reel and the component to rotate. A method for accessing media disposed on the reel includes pushing the reel away from a bottom portion of the storage device, pulling down on the component to disengage the first teeth from the second teeth, and rotating the reel to access the media.

Claims (14)

1. A storage device, comprising:

a housing having a top portion and a bottom portion:

a reel for holding data storage media, the reel disposed in the housing between the top portion and the bottom portion, the top portion having an inner surface, and the bottom portion defining a hole through which a bottom part of the reel is accessible; and

a lock component operable to engage the reel to prevent rotation of the reel relative to the lock component, to releasably engage the inner surface, and to disengage from the inner surface in response to a force on the lock component applied in a direction from the lock component towards the bottom portion,

wherein the inner surface is irrotatable with respect to the lock component when the lock component is engaged with the inner surface, and the inner surface is rotatable with respect to the lock component when the lock component is not engaged with the inner surface,

the lock component includes a generally cylindrical portion, the cylindrical portion having an outer surface with one or more protrusions, the reel includes a journal portion having an inner journal surface with one or more notches for interfacing with the one or more protrusions, the relative disposition of the notches and the protrusions providing for the sliding of the cylindrical portion of the lock component along the journal portion, and

the cylindrical portion of the lock component has a hollow interior, the inner surface having an alignment boss formed thereon, the boss protrudes from the inner surface into the hollow interior, and has an outer diameter, the outer diameter generally sized to an inner diameter of the hollow interior proximate the inner surface, and the outer diameter sized smaller more distal the inner surface.

2. The storage device of claim 1 , wherein the hollow interior is generally cylindrical, and the outer diameter of the boss tapers from proximate the inner surface to more distal the inner surface.

3. A storage device, comprising:

a housing having a top portion and a bottom portion:

a reel for holding data storage media, the reel disposed in the housing between the top portion and the bottom portion, the top portion having an inner surface, and the bottom portion defining a hole through which a bottom part of the reel is accessible; and

a lock component operable to engage the reel to prevent rotation of the reel relative to the lock component, to releasably engage the inner surface, and to disengage from the inner surface in response to a force on the lock component applied in a direction from the lock component towards the bottom portion,

wherein the inner surface is irrotatable with respect to the lock component when the lock component is engaged with the inner surface, and the inner surface is rotatable with respect to the lock component when the lock component is not engaged with the inner surface, and

the inner surface has an alignment boss formed thereon, the boss protruding from the inner surface generally perpendicularly, and tapering from a larger diameter proximate the inner surface to a smaller diameter more distal the inner surface.
