Embedded tape reel lock mechanism for tape embedded storage drive
The present disclosure generally relates to a lock mechanism for a tape embedded drive. The tape embedded drive comprises an enclosure enclosing a first tape reel, a second tape reel, and a lock mechanism. The first tape reel comprises a first gear, the second tape reel comprises a second gear, and the lock mechanism is disposed between the first and second gears. The lock mechanism comprises a latch lock, one or more latch tips disposed at a first end of the latch lock, a magnet disposed at a second end of the latch lock, and an electromagnet disposed adjacent to the magnet. When the electromagnet is activated, the latch lock moves to an unlocked position. When the electromagnet is de-activated, the latch lock moves to a locked position where the one or more latch tips are in contact with the first and second gears.
1. A storage device, comprising:
a first tape reel comprising a first gear;
a second tape reel disposed adjacent to the first tape reel, the second tape reel comprising a second gear; and
a lock mechanism disposed between the first gear and the second gear, the lock mechanism comprising:
a latch lock movable from a first position to a second position;
a magnet coupled to the latch lock; and
an electromagnet disposed adjacent to the magnet.
2. The storage device of claim 1 , wherein the latch lock comprises a first end and a second end opposite the first end, wherein the latch lock comprises one or more latch tips disposed on the first end, and wherein the magnet is disposed on the second end.
3. The storage device of claim 2 , wherein the one or more latch tips of the latch lock are rounded.
4. The storage device of claim 2 , wherein the one or more latch tips of the latch lock are in contact with the first and second gears in the first position and spaced from the first and second gears in the second position.
5. The storage device of claim 1 , wherein the electromagnet is activated to an on state when the latch lock is in the second position, and wherein the electromagnet is de-activated to an off state when the latch lock in the first position.
6. The storage device of claim 1 , wherein the electromagnetic is spaced a first distance from the magnet when the latch lock is in the second position, and wherein the electromagnet is spaced a second distance greater than the first distance from the magnet when the latch lock is in the first position.
7. The storage device of claim 1 , further comprising an enclosure, wherein the first tape reel, the second tape reel, and the lock mechanism are disposed within the enclosure.
8. A storage device, comprising:
a lock plate comprising a first surface and a second surface disposed perpendicular to the first surface;
a first tape reel disposed at least partially over the first surface of the lock plate;
a latch lock coupled to the first surface of the lock plate, the latch lock movable from a first position disposed in contact with the first tape reel to a second position spaced from the first tape reel;
a magnet coupled to the latch lock; and
an electromagnet disposed on the second surface of the lock plate adjacent to the magnet.
9. The storage device of claim 8 , wherein the electromagnet is activated to attract the magnet when the latch lock is in the second position, and wherein the electromagnet is de-activated to repel the magnet when the latch lock is in the first position.
10. The storage device of claim 8 , further comprising an enclosure, the first tape reel, the latch lock, the magnet, and the electromagnet being enclosed within the enclosure, wherein the first tape reel comprises a first gear and the latch lock is disposed in contact with the first gear in the first position.
11. The storage device of claim 10 , wherein the latch lock comprises one or more rounded latch tips, the one or more rounded latch tips being in contact with the first gear in the first position.
12. The storage device of claim 8 , wherein the latch lock comprises a first end and a second end opposite the first end, wherein the one or more latch tips are disposed on the first end the magnet is disposed on the second end.
13. The storage device of claim 8 , wherein the electromagnet and the magnet are spaced a first distance of about 0.4 mm to about 0.8 mm when the latch lock is in the first position, and wherein the electromagnet and the magnet are spaced a second distance of about 0.4 mm or less when the latch lock is in the second position.
14. A storage device, comprising:
an enclosure;
a first tape reel comprising a first gear disposed within the enclosure;
a second tape reel disposed within the enclosure adjacent to the first tape reel, the second tape reel comprising a second gear; and
means for locking the first tape reel and the second tape reel disposed within the enclosure, the means for locking comprising:
a latch lock movable from a first position to a second position;
a magnet coupled to the latch lock;
an electromagnet disposed adjacent to the magnet; and
means for activating the electromagnet.
15. The storage device of claim 14 , wherein the latch lock is in contact with the first and second gears in the first position and spaced from the first and second gears in the second position.
16. The storage device of claim 14 , wherein the means for activating the electromagnet switches the electromagnetic to an on state to attract the magnet when the latch lock is in the second position, and wherein the means for activating the electromagnet switches the electromagnet to an off state to repel the magnet when the latch lock is in the first position.
17. The storage device of claim 14 , wherein the latch lock moves a distance of about 0.4 mm to about 0.8 mm when moving from the first position to the second position.
18. The storage device of claim 14 , wherein the means for locking is disposed between the first and second tape reels.
19. The storage device of claim 14 , wherein the means for locking further comprises a lock plate, and wherein the latch lock, the magnet, and the electromagnet are coupled to the lock plate.
20. The storage device of claim 19 , wherein the first gear is disposed on a first surface of the first tape reel, the second gear is disposed on a first surface of the second tape reel, and the first and second gears are disposed adjacent to the lock plate.
