ABSTRACT:
A holographic data storage and/or retrieval apparatus having a spherical holographic recording medium and addressing means for rotating the recording medium to selectively expose the recording medium to data and reference beams at predetermined rotational positions. Whereby image data contained in the data beam is recorded in the recording medium and/or a data beam containing image data is reconstructed from the recording medium.
