摘要: A data reading method used in a reading device is provided. The reading device is for reading a hologram storage medium having a plurality of data pages, wherein each data page forms a data image having a plurality of image pixels on a sensing area of the reading device. The sensing area has a plurality of sensing pixels. The data reading method first determines a relative positional relationship between each image pixel and the sensing pixels or the optical quality of the corresponding data image of each image pixel. Next, a corresponding decoding unit of the sensing area is determined according to at least one of the relative positional relationship and the optical quality. Last, each image pixel is decoded by the corresponding decoding unit.

摘要: A data reading method used in a reading device for reading a holographic storage medium is provided. The holographic storage medium has several data areas. Each data area has several data pages, and each data page forms a data image that has at least one reserved block pattern on the reading device. The reserved block pattern of the data image corresponding to a first data page is searched within a first searching region to obtain a first pattern position. The reserved block pattern of the data image corresponding to a second data page is searched within a second searching region to obtain a second pattern position. A third searching position is then determined according to the first and second pattern positions. The reserved block pattern of the data image corresponding to a third data page is searched within a third searching region whose center is at the third searching position.
