Abstract: An information reproducing apparatus (1) is provided with: a reading device (10) for reading contents data; an operating device (41) constructed to rotate depending on an operation of a user; a detecting device (42) for detecting rotating operation performed on the operating device as operating signal (d); a generating device (22) for generating modulation signal (d?) by adding a predetermined additional signal (d?) vibrating at a fixed frequency or a variable frequency to the operating signal; a reproducing device (15) for reproducing the contents data, while determining reproduction speed and reproduction direction of the contents data on the basis of the modulation signal.

Abstract: An information reproducing apparatus (1) is provided with: a reading device (10) for reading contents data; an operating device (41) constructed to rotate depending on an operation of a user; a reproducing device (15) for reproducing the contents data, while determining reproduction speed and reproduction direction of the contents data on the basis of the operating signal which shows a rotating operation of the user performed on the operating device; and an adjusting device (22) for adjusting reproducing intensity of a plurality of data parts distributed in the contents data periodically or discretely during the reproduction of the contents data.

Abstract: An information reproducer (1) includes a element (15) for reproducing content data, a first setting element (20) for setting first loop reproduction unit data, a conversion element (20) for generating conversion data by dividing or elongating/contracting a plurality of unit beat data each corresponding to one beat included in first loop reproduction unit data, a second setting element (20) for setting second loop reproduction unit data where (i) the reproduction period is substantially identical to that of the first loop reproduction unit data, and (ii) a beat appears at a timing synchronous with that of a beat appearing in the first loop reproduction unit data by combining the conversion data, and a element (20) for controlling the reproduction element to perform loop reproduction of the first loop reproduction unit data and the second loop reproduction unit data.
