Abstract

A disk drive internal temperature control system is disclosed. The internal temperature control system includes a disk drive temperature monitor for determining a temperature of the disk drive and for providing a measure of the temperature of the disk drive and a disk drive temperature manager for managing the temperature of the disk drive based on the measure of the temperature of the disk drive. A temperature control component controls the temperature of the disk drive.

Claims

1. A disk drive internal temperature control system, comprising:

a disk drive temperature monitor for determining an internal temperature of said disk drive and for providing a measure of said temperature of said disk drive, said temperature monitor configured to operate within said disk drive;

a disk drive temperature manager for managing said temperature of said disk drive based on said measure of said temperature of said disk drive, said disk drive temperature manager configured to operate within said disk drive; and

a temperature control component configured to operate within said disk drive for controlling said internal temperature of said disk drive wherein said temperature control component initiates cooling of said disk drive in response to said disk drive reaching a first temperature and said temperature control component initiates heating of said disk drive in response to said disk drive reaching a second temperature.

2. The temperature control system of claim 1 wherein said disk drive temperature manager comprises:

a power accessor for continuously accessing power from a continuously available power source to power said temperature control system.

3. The temperature control system of claim 1 wherein said disk drive temperature monitor comprises a temperature sensor.

4. The temperature control system of claim 1 wherein said disk drive temperature manager comprises a thermostat.

5. The temperature control system of claim 1 wherein said temperature control component is selected from the group that includes a Peltier device, a selective drive integrated circuit (IC), and resistive heater.

6. The temperature control system of claim 1 wherein said internal components of said disk drive are selected from the group that includes spindle motor coils and actuator coils.

7. The temperature control system of claim 1 wherein said disk drive temperature monitor is mounted onto said disk drive.

8. A disk drive internal temperature control system, comprising:

means for monitoring a temperature of said disk drive and for providing a measure of said temperature of said disk drive, said means for monitoring configured to operate within said disk drive;

means for managing said temperature of said disk drive based on said measure of said temperature of said disk drive said means for managing configured to operate within said disk drive; and

means for controlling said temperature of said disk drive wherein a temperature control component initiates cooling of said disk drive in response to said disk drive reaching a first temperature and said temperature control component initiates heating of said disk drive in response to said disk drive reaching a second temperature wherein said means for controlling said temperature of said disk drive are configured to operate within said disk drive.

9. The temperature control system of claim 8 wherein said means for managing said temperature of said disk drive based on said measure of said temperature comprises:

means for continuously accessing power from a continuously available power source to power said temperature control system.

10. The temperature control system of claim 8 wherein said means for monitoring a temperature of said disk drive and for providing a measure of said temperature of said disk drive comprises a temperature sensor.

11. The temperature control system of claim 8 wherein said means for managing said temperature of said disk drive based on said measure of said temperature of said disk drive comprises a thermostat.

12. The temperature control system of claim 8 wherein said means for controlling said temperature is selected from the group that includes a Peltier device, a selective drive integrated circuit (IC), and resistive heater.

13. The temperature control system of claim 8 wherein said internal components of said disk drive are selected from the group that includes spindle motor coils and actuator coils.

14. The temperature control system of claim 8 wherein said means for monitoring said temperature is mounted onto said disk drive.

15. A hard disk drive (HDD) with an internal temperature control system for internal control of disk drive temperature, comprising:

a HDD;

a HDD temperature monitor disposed within said HDD for determining a temperature of said HDD and for providing a measure of said temperature of said HDD;

a HDD temperature manager disposed within said HDD for managing said temperature of said HDD based on said measure of said temperature of said HDD; and

a temperature control component disposed within said HDD for controlling said temperature of said HDD wherein said temperature control component initiates cooling of said HDD in response to said HDD reaching a first temperature and said temperature control component initiates heating of said HDD in response to said HDD reaching a second temperature.

16. The temperature control system of claim 15 wherein said HDD temperature manager comprises:

a power accessor for continuously accessing power from a continuously available power source to power said temperature control system.

17. The temperature control system of claim 15 wherein said HDD temperature monitor comprises a temperature sensor.

18. The temperature control system of claim 15 wherein said HDD temperature manager comprises a thermostat.

19. The temperature control system of claim 15 wherein said temperature control component is selected from the group that includes a Peltier device, a selective drive integrated circuit (IC), and resistive heater.

20. The temperature control system of claim 15 wherein said internal components of said HDD are selected from the group that includes spindle motor coils and actuator coils.

21. The temperature control system of claim 15 wherein said HDD temperature monitor is mounted onto said HDD.
