Abstract

The invention relates to the construction of an in-vehicle magnetic disk drive and a case for holding the in-vehicle magnetic disk drive. The in-vehicle magnetic disk drive must meet a condition peculiar thereto requiring normal operations under a very severe temperature condition. An environment of an excessively low temperature disturbs a normal information recording operation, while an environment of an excessively high temperature makes the retention of recorded information impossible.

A detachable magnetic disk drive is held in a case provided with a cold insulator, a heat insulator, a heat insulating material and a temperature sensor and is set in a specific position. When the magnetic disk drive is held permanently in place, the operation of the magnetic disk drive at temperatures outside a predetermined temperature range is inhibited so that the magnetic disk drive is permitted to operate only at temperatures in the predetermined temperature range. When the operation of the magnetic disk drive is inhibited, a signal is given to that effect. The magnetic disk drive and the case can be disposed in a vehicle.

Claims

1. A case for holding a magnetic disk drive, comprising a cold insulator for keeping the magnetic disk drive cool or a heat insulator for keeping the magnetic disk drive warm.

2. The case according to claim 1, wherein the magnetic disk drive can easily be put in and taken out of the case.

3. The case according to claim 1 further comprising a temperature sensor.

4. The case according to claim 1, wherein the cold insulator or the heat insulator serves also as a shock absorber.

5. A magnetic disk drive holding method of holding a magnetic disk drive including rotating magnetic disks, magnetic heads for writing or reading information to or from the magnetic disks, and a carriage for moving the magnetic heads on the magnetic disks, said method including holding the magnetic disk drive such that the magnetic heads move vertically.

6. A magnetic disk drive mounting method of mounting a magnetic disk drive contained in a case and including rotating magnetic disks, magnetic heads for writing or reading information to or from the magnetic disks, and a carriage for moving the magnetic heads on the magnetic disks on a vehicle, said method comprising the steps of:

forming an opening in the case; and

disposing the case near an air vent of an air conditioner included in the vehicle.

7. The magnetic disk drive mounting method according to claim 6, wherein the case is provided with a cold insulator for keeping the magnetic disk drive cool or a heat insulator for keeping the magnetic disk drive warm.

8. A case for holding a magnetic disk drive, provided with a heater interposed between the case and the magnetic disk drive.

9. The case according to claim 8, wherein the magnetic disk drive can easily be put in and taken out of the case.

10. The case according to claim 9 further provided with a temperature sensor.

11. A magnetic disk drive packed in an outer package, provided with a heater interposed between the magnetic disk drive and the outer case.

12. The magnetic disk drive according to claim 11 further provided with a temperature sensor.
