10. A content acquisition apparatus for acquiring content data from a content providing medium having a hologram memory in which the content data is recorded as distribution data, comprising:
-
reference light outputting means for outputting reading out reference light to said hologram memory on the content recording medium;
detection means for detecting, in a state wherein the reading out reference light is applied to said hologram memory by said reference light outputting means, a reproduction image based on data recorded in said hologram memory; and
reproduction processing means for reproducing a data string as the content data from the reproduction image detected by said detection means. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
