STORAGE CARD AND DEVICES

摘要

A data-card system is disclosed which includes a data access head-arm (152) for performing a rotational movement for accessing data recorded on a recording medium (180) over an arc segment of the rotational movement. The recording medium (180) includes a plurality of data tracks for storing the data therein and each of the tracks is substantially an arc-segment substantially parallel to a neighboring track. The data-card system further includes a movable carriage (115) for carrying out a horizontal linear movement of the data access head-arm (152) for access of the plurality of data tracks on the recording medium (180).
