Abstract: A system (102) comprising a box (104) for implanting in a mamMal body part (106), which box is provided with a first electrical contact (110, 121, 114, 116, 118, 120), and a module (108) for accommodating in the box, which module is provided with a second electrical contact (122, 124, 126) for cooperation with said first electrical contact. The first electrical contact and the second electrical contact are mutually movable, at least in a stationary accommodation of the module in the box, between a contact position in which said first and second electrical contacts are electrically connected, and a non-contact position in which said first and second electrical contacts are separated from each other.

Abstract: The present invention provides an optical recording medium (10), comprising at least one recording layer (16) being adapted to form marks upon radiation of a laser beam having a particular recording wavelength, wherein a material constituting the recording layer (16) has an absorption maximum at a wavelength that is 100 nm to 250 nm higher than the recording wavelength. Moreover, the invention describes the use of a material for forming such an optical recording medium (10).

Abstract: A record carrier 21, a recording method and a recording device are provided for qualitative and record carrier independent high speed data recording. The record carrier 21, such as an optical record carrier, comprises at least one information area 210 with at least one reference 2100 to a class 22 of write strategy providing a direction instruction to optimize recording process. The recording method represents an intelligent write strategy optimization method seeking after a suitable write strategy for the record carrier by use of the reference 2100 to a class 22 of write strategy as a backup information on beforehand and by use of details on the recording device being operative for executing the recording method. Coupling of the information about the recording device and the record carrier increases the quality of written data, and the recording method optimizing the write strategy becomes considerably faster when information about the record carrier is known on beforehand.
