A data storage apparatus adopting a time division multiplexing technique, and a data recording method and a data reproduction method both using the apparatus, are provided. In the data storage apparatus, a recording medium stores data, and a stage supports the recording medium. A scanner drives the stage, and a cantilever array composed of a plurality of cantilevers record data to and reproducing data from the recording medium in a data detecting sequence. A controller detects data by applying a scanner driving signal to the scanner and applying a voltage signal for data recording or a voltage modulation signal for data reproduction to the plurality of cantilevers. Controlling the plurality of cantilevers using a single controller enables a data storage apparatus to be driven with low power and reduced in its circuit size. Installation of a pseudo-differential capacitor ensures high sensitivity. Since data is recorded and reproduced while the scanner moves at a uniform speed, and the data are recorded in a specific pattern, this leads to fast data recording and reproduction.
