Abstract
Abstract A magnetooptical storage element (K) having a recording layer (1, 3, 6, 7, 8) of a multi-layer construction including a reflective layer (8). The reflective layer (8) is made of an aluminium-nickel alloy obtained by adding nickel to aluminium such that the aluminium-nickel alloy contains approximately 2 to 10 atomic percent of nickel.
