| 摘要 |
<p>The invention concerns a method for indicating on a data medium (9) a sector referenced by a binary word (16) consisting of M number of multiplets comprising each L number of bits, comprising operations which consist in engraving on the data medium locally at said sector, a succession of M multiplets corresponding each to a first multiplet, each second multiplet being equal to a vector of N components, each of value +1 or -1, such that N = 2L- 1 and such that the scalar product of said vector by any other vector to which is equal another second multiplet, is not more than a + 1. The data medium (9) is for example an optical disc.</p> |
