Abstract
An exchangeable hard disk drive including a disk cartridge functioning as a hard disk and a driving device which drives the disk cartridge and prevents external vibration from being transmitted to the disk cartridge. The driving device has a holder into which the disk cartridge is inserted and from which the disk cartridge is ejected and the holder is supported vibro-isolatingly by a vibro-isolating member. In addition, when the disk cartridge is inserted into the holder, they are coupled together. Therefore, the disk cartridge is indirectly supported vibro-isolatingly when the disk cartridge is inserted into the holder. Consequently, the disk cartridge is hardly subjected to the external vibration.
