A data storage and retrieval system reads and/or writes data onto a data storage disk defining a recording surface having a radial dimension and at least one data track directed generally transverse to the radial dimension. The system includes a housing having an interior for receiving the one data storage disk. The disk is rotated upon being received in the housing interior. A head array having a plurality of read and/or write heads is arranged in a longitudinal dimension, for communicating with the recording surface of the data storage disk. A head array support arm is disposed within the housing interior, for supporting the head array adjacent the recording surface of the storage disk, with the longitudinal dimension of the arrangement of heads extending in a cross-track direction of the disk recording surface and spanning more than one half of the radial dimension of the recording surface. An actuator is coupled to selectively move the head array support arm and head array in a cross-track direction. |
