Abstract: PURPOSE: To achieve downsizing and easy manufacturing of a disk device by folding a flexible printed circuit into halves and demarcating the both ends to a first connector provided on a housing wall. CONSTITUTION: A writing signal to a recording surface of a magnetic disk 6, or a reading signal from a recording surface on the disk 6, and electric power to actuator 8 are transmitted from an electronic circuit card 3 attached on the back of the housing 2 or transmitted to the card 3 via two rows of pins 9b planted on a substrate 4 via an insulator 9a in order to electrically communicate the inside and outside of the housing 2 with each other. The two rows of pins terminals 9b planted on this substrate 4 constitutes a first connector 9. A flexible printed circuit 11 is connected with the rows of pin terminals 9b projecting inside the housing 2. A connector 10 attached to the card 3 is connected with the terminal rows 9b projecting outside of the housing 2.

Abstract: PURPOSE: To make the device thin-structure and easy to manufacture by providing the device with a first connection means to connect the other end of an external cable through a housing wall and providing the card with a second connector to be engaged with the first connector. CONSTITUTION: A magnetic disk device 1 has a housing 2 and a card 3 which is equipped with a control purpose electronic circuit and is installed on an external bottom of the housing. The housing 2 consists of a substrate 4 and a cover 5. In the housing 2, a spin motor 6 indicated by the substrate 4, a magnetic disk, a signal conversion head, and actuator are incorporated. An electric power to these devices is supplied from an electronic card circuit 3 or to the card 3 installed on the back of the housing 2 via the two rows of pin terminals 8b and 9b planted on a substrate 4 for electrically connecting the inside and outside of the housing 2. The terminal 9b constitute a first connector 9. The terminal rows 8b and 9b are connected with the printed circuit 11 in the housing 2 via a third connector 12 fixed at one end of the circuit 11.

Abstract: PURPOSE: To achieve a low-profile disk storage device. CONSTITUTION: A housing in which a head disk assembly is incorporated is to be electrically connected with a card 3 equipped with an electronic control circuit. For this purpose, a substrate 4 of the housing is provided with a first connector 9; a second connector 10 is provided in a through hole 3e made in the card 3, being projected from both opening ends of the through hole 3e, and both connectors are engaged. Consequently, the whole disk storage device can be made thinner by the thickness of the card.
