ABSTRACT:
A disk assembly comprising a spindle disposed rotatably around a fixed axis. The spindle comprises a rim formed at a lower portion of the spindle and a flange spaced axially above the rim. At least one disk having a recording surface for recording data is positioned on the spindle. The at least one disk has an upper side facing the flange and a lower side facing the rim. A resilient clamping member is positioned so that an upper end faces the flange and a lower end faces the upper side of the at least one disk. In addition, a compliant element is supported by the rim. The compliant element is supported by the rim so that the upper portion of the compliant element is compressed toward the upper surface of the rim by the bias of the resilient clamping member under normal operation and so that, during a high shock capable of separating the at least one disk from the upper surface of the rim, the compliant element fills at least a portion of the space between the lower side of the at least one disk and the upper surface of the rim.
