Abstract
Abstract A disk drive for information storage having at least one disk for recording data and a head actuator which includes a read/write head for reading and writing data to the disk. The disk drive includes an accessory member, such as a filter or spoiler, which is formed with an attaching part. A cabinet is used for housing therein the disk, head actuator, and accessory member. The cabinet is divided into a first cabinet part and a second cabinet part, such that the attaching part of the accessory member is sandwiched or interposed between the first and second cabinet parts and located in position inside the cabinet when the two cabinet parts are joined together. Thus, the accessory member can be attachably positioned to the disk drive inside the cabinet without using screws or other timeconsuming and costly assembly techniques.
