 Light, miniaturized products |
|
Portability is an essential concept in developing notebook PCs. They are carried from place to place, and the lighter and more compact the product is made, the better it is. To that end, the case needs to be thin. But it also has to be able to withstand external forces such as dropping, shock, and pressure that may cause damage.

| Lengthening product life |
|
The gap between the head and the disk in a hard disk drive is only about a nanometer. For this reason, the hard disk drive is one of the most delicate parts in the PC. If damages to the hard disk drive is decreased, the life of the PC will be lengthened.

| Commitments for Toshiba PC |
|
In order to achieve a slim product design we had to increase its strength, although we encountered the difficulties in realizing greater high-density packaging while halving the thickness of the product.

 |
| Realizing a case only 0.6mm thick |
|
Metal retains strength even when formed thin, but it is still relatively heavy and not a good material for portable products in general. We use magnesium alloy for our PCs, a metal, but light, to achieve 0.6mm thinness with acceptable hardness. We brought the magnesium die-casting process to mass production, and realized a 0.6mm thinness case.
We did this by adopting technology such as the "film gate" - a thin, wide opening for pouring magnesium.

Reduction of residual materials on printed circuit boards
|
In manufacturing printed circuit boards, residual materials cannot be avoided. We are making efforts to minimize them. This example shows a case where we succeeded in a 50% reduction compared to the previous board through changes in the board layout and improvement of production facilities.

Protect Hard Disk Drives from accidental shock
|
The hard disk drive is a precise electro-mechanical device, and one of the most delicate parts of the PC. We have introduced a three-dimensional acceleration sensor for monitoring the position of a notebook PC. Inclination of the notebook PC that could lead to damage to the hard disk drive is calculated, and if it is reached - if the PC falls from a desk for example - the read/write head is retracted from the surface of the disk, avoiding damage to the disk or the head.
