Magnetic Disk Recorders for data and video recording on-board airborne vehicles are described in this presentation. The DS4000 Hard Disk System (HDS) is designed for high capacity and high bandwidth data storage and can be configured to accommodate various sensors inputs. It is based upon high-end 3.5” magnetic disks packaged in a a ruggedized housing to withstand severe environmental conditions. The disk cartridge is removable and directly compatible with standard computer interfaces (SCSI /EIDE). The VS2000 Video Hard Disk System (VHDS) is a customized version dedicated to acquisition of 1 to 4 video channels and auxiliary data. It consists of a 2.5” disk drive cartridge coupled with digitization and video compression modules. It efficiently replaces up to 4 analog video recorders by a single compact box, which can be easily fitted in a very small volume. Retrieval and simultaneous display of video data is made on a standard PC system. A data recording version DS 2000 of the video recorder is to be used in the small payload application .The DS 2000 Ultra Compact Airborne recorder can acquire and record any type of digital data up to 60 Mb/s First tests in actual flight conditions have recently demonstrated the robustness of the disk recorder.
