Abstract

The flexible membrane comprises at least one thin layer with a plurality of indentations formed therein, wherein bearing points for actuating elements are disposed between said indentations in order to locally deform the membrane. The thus open-worked membrane is more flexible in a cross direction. The open-worked membrane can act as a support for the recording data, cooperating with a micro-point bi-dimensional network.
