Title: Disk device
Inventor: ONO HIROBUMI
IPC: G11B7/135
Filed: 1993-02-10
Abstract: PURPOSE:To make the disk device thin structure by entering an objective lens of an optical pickup and some parts of a lens holder and a magnetic circuit into a cartridge via an opening part for the pickup of the cartridge at the time of loading a disk. CONSTITUTION:Regarding the optical pickup 17, the thickness of the pickup 17 is reduced by protruding outward a part of the lens holder 21 and a part of the magnetic circuit from a cover 24. Then, since the protruding parts of the holder 21 and the magnetic circuit are entered via the opening part 5 for the pickup into the cartridge, it is not necessary to expand a space between the cartridge 3 and the upper surface of the optical pickup 17 because of the protruding parts. Moreover, an optical system block part 18 and an objective lens driving block are provided in juxtaposition along the surface of the disk 2. By this method, the thickness of the optical pickup 17 itself can be thinned, and hence the device as the product itself can be formed thin.

Abstract: PURPOSE:To unite elements and miniaturize a detector, by forming an infrared detecting element on one of layers with multi-semiconductor piles different in forbidden band-width each other, providing an active circuit element on the other layer having a wider forbidden band-width than a layer where it is formed, and connecting them electrically.

Next, a small-area, upper layer 22 of Hg0.8Cd0.2Te is grown in epitaxial on it. An infrared detecting element is provided thereon. The surfaces of layers 21, 22 are covered with insulating films 23, 24 respectively. The forbidden band-width of the layer 21 for circuit element provision is chosen larger than that of the layer 22 for detecting element formation in this fashion. And yet, this provides unity on the same single crystal thin-plate 20. These connections are facilitated and their sizes are reduced.
