Abstract

A disc drive arrangement 10 for accessing information from and recording information onto a disc 25 retained in a cartridge 27 comprises a linkage 22 operatively connecting a door 18 to a head 26, 28 mounted on a carriage 24 for urging the head 26, 28 away from the cartridge 27 when the door 18 is opened. The linkage includes an arm 154 with a cam surface 158 which urges the head 26, 28 away in an accelerated manner. A dashpot 188 operably connected to the head 26, 28 and linkage 22 allows the head 26, 28 to dampingly settle on the disc 25 after the dome 18 is closed.
