ABSTRACT:
A magnetic disk drive assembly has an ejector pivotably mounted on a base for movement between a locked position and an unlocked position, the ejector being normally spring-biased toward the unlocked position. When a diskette is fully inserted into the magnetic disk drive assembly, the ejector is displaced by the diskette into the locked position. A locking projection is mounted on the base for locking the ejector in the locked position. A hub frame pivotably mounted on the base supports a lock release member resiliently engageable with the ejector when the latter is in the locked position and also when the hub frame is in a drive position. When the hub frame is moved from the drive position to a non-drive position, the lock release member allows the ejector to be released from the locked position to the unlocked position and also released from the lock release member.
