The invention relates to a data storage device with the above-mentioned features of

Protection claim 1.

Voyage data recorders are used on board ships or in airplanes in order to record the security-relevant data of the ship or the aircraft and to be able to reproduce the last data before the event in the event of an accident or an accident. These data storage devices comprise for this purpose on the one hand recording devices for the acquisition and storage units for the storage of data. The data storage devices also have a housing in which the recording devices or the storage unit are arranged. The data storage devices, also known as data recorders or black boxes, are particularly impact-resistant, temperature-resistant and seawater-compatible, which requires special insulation of the housing. The insulation is traditionally on the inside of the

Housing or arranged by housing parts. The storage unit is provided inside the housing. A disadvantage of the known data storage devices that no immediate insulation or backup of the storage unit is provided, which often leads to damage or loss of the stored data. In addition, the memory units often can only be removed from the data storage device by those skilled in the art using specialized tools. For this purpose, the data storage devices must be sent either in special workshops or the maintenance or repair personnel are brought to the data storage devices, which is when using the data storage device on ships is particularly complex and difficult. The maintenance and repair of conventional

Data storage devices is particularly cost intensive and complicated.

It is therefore an object of the present invention to provide a data storage device which has a specially protected storage unit which, moreover, can be removed from the data storage device particularly easily.

This object is achieved by a data storage device having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The data storage device according to the invention comprises a housing with at least two detachably connected housing parts and a storage unit removably arranged in the housing. In addition to the storage unit, there is also the possibility that in the housing or at least in parts thereof additional devices, such as recording or evaluation devices

BESTAUGUNGSKO E are arranged. The data storage device according to the invention is characterized in that a form-fitting insertable in at least one housing part insulating element is provided. The insulating element is thereby inserted in particular into the housing part or the housing and has at least one recess into which a storage medium can be inserted.

It is provided that the storage medium is formed positively inserted into the recess, including in particular a plug-in or retractable training of

Storage medium offers. The insulating element of the data storage device according to the invention comprises or encloses the storage medium completely and thus provides comprehensive protection of the storage medium from damage. In combination with the housing enclosing the insulating element and the storage medium accommodated therein results in a high impact resistance, fire resistance and resistance to low temperatures, water density and seawater suitability of the entire storage device according to the invention. Due to the simple insertion and in particular the insertion of the insulating element in at least one housing part, this can be very easily removed from the data storage device, so that there is also the possibility that arranged in the element

To remove storage medium in a particularly fast manner from the data storage device to maintain the storage medium to check its function to read the stored data or to exchange the storage medium, for example, against a storage medium with higher storage capacity. Since the storage media have increased storage capacities due to progressive developments with reduced dimensions, an increase of the available storage space is considerably simplified. It can this purpose in the originally provided recess in the insulating element without reworking

dimensionally equivalent storage medium with higher storage capacity or two or more small storage media are inserted.
