Abstract

The invention relates to a method of recovering data from an information carrier having data stored according to data pages, each data page being formed by a set of data being spatially distant from each other, said method comprising the steps of reading (501) at least one data page so as to generated at least one read data page, storing (505) said at least one read data page in a storage memory, recovering (507) data from said at least one read data page stored in said storage memory.
