The present invention relates to hard disk drive (HDD) and digital versatile disk (DVD) systems, and more particularly to audio monitoring of HDD and DVD systems.

The background description provided herein is for the purpose of generally describing the invention. The operation of the inventor of the present invention, the extent of the description in the background art, and the fact that it is not applicable to the prior art in the present application, is not explicitly or implicitly considered to be a prior art of the present invention.

Referring now to Figure 1, it is shown that the HDD system 10 includes a HDD printed circuit board (PCB) 14. Buffer 18 stores read, write, and/or volatile control data associated with control of HDD system 10. The buffer 18 typically uses volatile memory with low latency. For example, Synchronous Dynamic Random Access Memory (SDRAM) or other types of low latency memory can be used. Non-volatile memory 19, such as flash memory, may also be provided to store key material such as non-volatile control codes.

The processor 22 disposed on the HDD PCB 14 performs data and/or control processing related to the operation of the HDD system 10. A hard disk control module (HDC) 26 is in communication with the input/output interface 24 and is in communication with a spindle/voice coil motor (VCM) driver or module 30 and/or a read/write channel module 34. The HDC 26 coordinates the control of the spindle/VCM driver 30, the read/write channel module 34, and the processor 22, and inputs/outputs data to and from the host 35 via the interface 24.

During a write operation, the read/write channel module 34 encodes the data to be written to the read/write device 59. The read/write channel module 34 processes the write signal for reliability, and for example, error correction coding (ECC), operational length limiting coding (RLL), and the like can be applied. During a read operation, the read/write channel module 34 converts the analog read signal output of the read/write device 59 into a digital read signal. The converted signal is then detected and decoded via known techniques to recover the data written on the HDD.

A hard disk drive assembly (HDDA) 50 includes one or more hard disk drives 52 that include a magnetic coating that stores a magnetic field. The disc 52 is rotated by the spindle motor 54. In general, spindle motor 54 rotates hard drive disc 52 at a controlled rate during a read/write operation. One or more read/write arms 58 are moved relative to the disc 52 to read data from the hard drive disc 52 and/or to write data to the hard drive disc 52. The spindle/VCM driver 30 controls the spindle motor 54 of this rotating disc 52. The spindle/VCM driver 30 also generates a control signal that, for example, uses a voice coil actuator, a stepper motor, or any other suitable actuator to position the read/write arm 58.

A read/write device 59 is located near the distal end of the read/write arm 58. The read/write device 59 includes a write element, such as an inductor that generates a magnetic field. The read/write device 59 further includes a read element (e.g., a magnetoresistive (MR) element) that senses the magnetic field on the disc 52. The HDDA 50 includes a preamplifier circuit 60 that amplifies an analog read/write signal. When reading the data, the preamplifier circuit 60 amplifies the low level signal from the read element and outputs the amplified signal to the read/write channel module 34. At the time of writing the data, a write current flowing through the write element of the read/write device 59 is generated. The write current is switched to produce a magnetic field with positive or negative polarity. The positive or negative polarity is stored by the hard disk 52 and is used to represent the data.

Referring now to FIG. 2, which shows a digital versatile disc (DVD) system 110 including a DVD PCB 114, the DVD PCB 114 includes a buffer 118 that stores read data, writes data, and/or is volatile associated with DVD system 110 control. Control code. Buffer 118 may use volatile memory such as SDRAM or other types of low latency memory. Non-volatile memory 119, such as flash memory, can also be used to store key material, such as data related to DVD write formats and/or other non-volatile control codes.

The processor 122 disposed on the DVD PCB 114 performs data and/or control processing related to the operation of the DVD system 110. Processor 122 also performs copy protected decoding and/or compression/decompression as needed. The DVD control module 126 is in communication with the input/output interface 124 and with the spindle/feed motor (FM) driver 130 and/or the read/write channel module 134. The DVD control module 126 coordinates: control of the spindle/FM driver 130, the read/write channel module 134, and the processor 122, and data input/output via the interface 124.

During a write operation, the read/write channel module 134 encodes the material to be written to the DVD disc by an optical read/write (ORW) device or an optical read only (OR) device 159. The read/write channel module 134 processes signals for reliability, and may apply, for example, ECC, RLL, and the like. During a read operation, the read/write channel module 134 converts the analog output of the ORW or OR device 159 into a digital signal. The converted signal is then detected and decoded by known techniques to recover the data written on the DVD.

The DVD assembly (DVDA) 150 includes a DVD disc 152 that optically stores material. The disc 152 is rotated by the spindle motor 154. Spindle motor 154 rotates DVD disc 152 at a controlled and/or variable rate during a read/write operation. The ORW or OR device 159 is moved relative to the DVD disc 152 to read data from the DVD disc 152 and/or to write data to the DVD disc 152. The ORW or OR device 159 typically includes a laser and an optical sensor.

For DVD read/write and DVD read-only systems, during a read operation, the laser is directed to a track on the DVD containing land and a pick. The optical sensor senses reflections caused by land/pits. For DVD read/write (RW) applications, it is also possible to use a laser to heat the stamp layer on the DVD disc during a write operation. If the stamp is heated to a certain temperature, the stamp is transparent and represents a binary digital value. If the stamp is heated to another temperature, the stamp is opaque and represents another binary digital value.

The spindle/FM driver 130 controls a spindle motor 154 that controllably rotates the DVD disc 152. The spindle/FM driver 130 also generates a control signal that is used to position the feed motor 158, for example, using a voice coil actuator, a stepper motor, or any other suitable actuator. Feed motor 158 typically moves ORW or OR device 159 radially relative to DVD disc 152. The laser driver 161 generates a laser drive signal in accordance with the output of the read/write channel module 134. The DVDA 150 includes a preamplifier circuit 160 that amplifies an analog read signal. When reading the data, the preamplifier circuit 160 amplifies the low level signal from the ORW or OR device and outputs the amplified signal to the read/write channel module 134.

The DVD system 110 further includes a codec module 140 that encodes and/or decodes video of any of these MPEG formats. The audio and/or video digital signal processors and/or modules 142 and 144 perform audio and/or video signal processing, respectively.

Other areas of application will be apparent from the detailed description provided below. The detailed description and the specific examples are intended to be illustrative and not restrictive

The invention will be more fully understood from the following detailed description.

The following description is of a typical nature only and is not intended to limit the invention, its application or use. For the sake of clarity, the same reference numbers are used in the figures to identify similar elements. As used herein, the term: a module, circuit, and/or device means: a special purpose integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and a memory that is executed. One or more software or firmware programs, combined logic circuits, and/or other suitable components that provide the described functionality. As used herein, the phrase "at least one of A, B, and C" shall be taken to mean the use of non-exclusive logical OR (A or B or C). It is to be understood that the steps in one method may be performed in a different order without changing the principles of the invention.

The microphone monitors noise generated by components of the hard disk assembly (HDDA) and/or DVD assembly (DVDA). Due to the mechanical nature of HDDA and/or DVDA, noise generated by motors, servo movements, air disturbances, intermittent head collisions, loose components, and/or various mechanical resonances can be identified using the audio monitoring module described below. . The audio monitoring module can increase or decrease the rate of the component by a predetermined amount or percentage when the resonant mode of the component is detected. The predetermined amount can include a fixed value, a fixed percentage of the current rate, a variable value or percentage, a progressive value, and/or other suitable value.

For example, an audio monitoring module can use subband analysis. The operation of HDD and DVD systems can be improved by monitoring signal levels, frequency and noise patterns, and changes in monitored parameters as a function of time. These systems automatically adjust HDD or DVD operating parameters to reduce sound noise. By doing so, the user's troubles can be reduced. During the use of different HDD or DVD systems, the adjustment operation of the HDDA or DVDA away from the resonant mode of the mechanical components can be optimized. In addition, immediate monitoring of the motor and/or servo noise can be used to predict future fault events. Analysis of historical data can be performed to estimate and monitor aging of HDD or DVD systems.

Audio monitoring modules can also be used as a relatively low cost method for distinguishing product quality. For example, the method can be used to separate high quality or low quality drives from other medium quality drives. Low noise devices tend to be more reliable for devices with higher noise, especially for HDD or DVD systems with the same or similar design. In addition, immediate monitoring of mechanical components can be used to improve future quality levels. Although a DVD system is discussed herein, the invention is also applicable to a compact disc (CD).

The microphone can be embedded on the HDDA or DVDA and/or embedded in a printed circuit board assembly (PCBA) of the HDD or DVD system. If embedded in HDDA or DVDA, the microphone can share a flexible connector to reduce cost. In addition, audio analog-to-digital converters (ADCs) can be embedded in system-on-a-chip (SOC), motor controllers, and/or power management modules to reduce system cost.

Referring now to Figure 8, a typical audio monitoring module 420 in accordance with the present invention is shown. The audio monitoring module 420 receives the output of the microphone 422. The audio monitoring module 420 includes an analog-to-digital converter (ADC) 424 that converts the analog output of the microphone to a digital audio signal. Analysis module 428 receives the digital audio output of analog-to-digital converter 424. Analysis module 428 selectively transmits the data to memory 434 and receives the data from memory 434. The memory can be analyzed locally, and/or can be a shared memory such as volatile memory and NV memory. The parameter adjustment module 430 selectively adjusts operating parameters of the HDD or DVD device according to the analysis.

The analysis module 428 can include a subband analysis module 442 that monitors signal levels, frequency and pattern of noise occurrences, changes in monitored parameters as a function of time, and/or other functions of monitored parameters. . The pattern can include resonance or other criteria at a particular frequency.

The fault prediction module 444 selectively predicts faults based on current and/or historical noise information and/or its functions. For example, the fault prediction module can perform heterodyne based on current and/or historical data and estimate the expected fault date. The quality analysis module 448 can estimate the quality of the HDD or DVD device based on the measured current and/or historical noise information and/or its function. The age estimation module 452 estimates the age of the device based on current and/or historical noise information, changes in current or historical information, and/or other functions of current and/or historical noise information. Age can be related to expected depreciation or useful life. For example, the age estimation module 452 can monitor changes in the level of noise as a function of time. The noise level can be compared to functions, data, curves, or other stored information to estimate the age of the device or component.

The correlation module 453 can be used to compare the current noise information with the stored noise information to identify a specific fault. The memory module 434 can store a noise profile associated with a possible failure mode. The correlation module 453 can relate the current and/or historical noise contours to the stored contours. When the correlation result exceeds a predetermined correlation value, the relevant module can output a fault message, initiate diagnosis, and/or take other actions.

Referring now to Figure 9, this flow chart illustrates the steps of a typical method for adjusting HDD or DVD operating parameters based on the sensed noise information. Control begins in step 500. In step 502, control determines whether the device is operating. In step 504, control converts the audio signal to a digital audio signal. In step 506, control analyzes the digital audio signal. In step 508, control determines if a problem has been detected. In other words, the control determines whether the noise information indicates a problem. For example, the monitored noise parameters exceed the critical value. If true, then control adjusts the operating parameters of the HDD or DVD device in step 509. For example, the rate of rotation, scan rate, voltage level, current level, or any other parameter can be adjusted. If step 508 is false, then control continues with step 510 and a determination is made as to whether there is a potential future failure based on current and/or historical noise information and/or its function. If step 510 is true, then control transfers the message to the host device in step 514, and/or adjusts the operational parameters of the HDD or DVD device.

Referring now to Figure 10, this flow chart illustrates the steps of a method for determining the quality of a device of an HDD or DVD system based on the sensed noise information. Control begins in step 530. In step 532, control determines if the device is operating. If true, then control converts the audio signal to a digital audio signal in step 534.

In step 538, control analyzes the digital audio signal. In step 540, control compares the current and/or historical noise information and/or its function to a first threshold. If the noise level is below the first threshold, then control sets the quality to the first quality value in step 542. If step 540 is false, then control determines in step 550 whether the current and/or historical noise information is greater than the first threshold but less than the second threshold. If true, then control sets the quality to a second quality value in step 554. Otherwise control sets the quality to a third quality value in step 560. Although three quality values or levels are described, additional or fewer quality values may be used. Quality values or levels can be used for variable pricing and/or other market decisions.

Referring now to Figure 11, a flow chart illustrates the steps of a method for estimating aging of an HDD or DVD system based on current and/or historical noise levels. Control begins in step 580. In step 584, control determines if the device is operating. In step 586, control converts the audio signal to a digital audio signal. In step 590, control analyzes the digital audio signal. In step 594, control compares the current and/or historical noise levels to predetermined thresholds, functions, or other predetermined criteria. In step 596, control estimates the age of the HDD or DVD system and/or one or more of its components based on the comparison.

Referring now to Figure 12, a flow chart illustrates the steps of a method for estimating future failures of an HDD or DVD system based on current and/or historical noise levels. Control begins in step 600. In step 604, control determines whether the device is operating. In step 606, control converts the audio signal to a digital audio signal. In step 610, control analyzes the digital audio signal. In step 614, control extrapolates future performance based on current and/or historical noise levels and compares the extrapolated results to predetermined thresholds, functions, or other predetermined criteria. In step 616, control estimates future failures of the HDD or DVD system and/or one or more of its components based on the comparison. For example, the control can provide an estimated failure date or an estimated number of operating hours until the failure.

Referring now to Figure 13, device 700 is shown to include a printed circuit board (PCB) (not shown) or motherboard 704. By way of example only, device 700 may be a computer system, network switch, router, server, or other type of electronic device including integrated circuitry that is disposed on a rack and/or housing and that is cooled using a fan . One or more integrated circuits 708 may be disposed on the motherboard 704.

By way of example only, integrated circuit 708 may include a central processing unit (CPU), a special purpose integrated circuit (ASIC), a graphics processing unit (GPU), and/or other types of integrated circuits. The heatsink 712 is thermally coupled to the integrated circuit 708 and absorbs heat therefrom. Fan 716 circulates air above radiator 712 to dissipate heat.

One or more other types of integrated circuits, such as graphics processing unit (GPU) 718, may be disposed on motherboard 704. Heat sink 722 is thermally coupled to GPU 718 and transfers heat therefrom. Fan 726 circulates air above radiator 722 to dissipate heat. The motherboard 704 can be disposed on the rack and/or in the housing 730. One or more additional fans 734 may provide additional cooling inside the housing. Other elements 744, such as a memory module and/or other modules or devices (not shown), may be disposed on the motherboard 704.

In operation, integrated circuit 708 can include an audio monitoring module 750 that monitors the audio signals produced by fans 716, 726, and/or 734. The microphone 754 can be disposed inside the housing 730. Alternatively, the microphone 756 can be disposed outside of the housing 730. Alternatively, the speaker 758 can be used as a microphone. Sound waves from the impact speaker 756 can be sensed and used for analysis.

The integrated circuit 708 and/or GPU 718 can include an audio monitoring (AM) module 750 that performs audio analysis on the audio signals as described above. Alternatively, the AM module 750 can be a standalone device or integrated with any other component or integrated circuit. The AM module 750 can perform subband analysis. The operation of the fan can be improved by monitoring signal levels, frequency and noise patterns, and changes in monitored parameters as a function of time.

Fan operating parameters can be automatically adjusted to reduce noise. By doing so, the user's troubles can be reduced. Fan operation away from the resonant mode can be performed. In addition, immediate monitoring of fan noise can be used to predict future failure events. Analysis of historical data can be performed to estimate and monitor the aging of the fan.

Audio monitoring can also be used as a relatively low cost method for distinguishing product quality. For example, use this method to separate high quality or low quality fans from other medium quality fans. Low noise devices tend to be more reliable for devices with higher noise, especially for fans with the same or similar design. In addition, immediate monitoring of mechanical components can be used to improve future quality levels.

Although HDD and DVD systems are disclosed, the invention is also applicable to other rotating storage devices, magnetic storage devices, and/or optical storage devices.

In addition to or instead of changing the operational parameters of the components as described above, the audio monitoring module can generate signals to provide an indication of how the components are operating. By way of example only, the audio monitoring module can generate an indication signal to the host device when the component is emitting this typically acceptable level of noise. By way of example only, when the fan is sending too much noise, the CPU can send an error message to the operating system (OS) to notify the OS and/or the user.

The audio monitoring module can provide a list of actions that can be taken by the user. For example, an audio monitoring module can allow a user to select from a number of different options. Some options may include operating in a restricted mode, such as a low power mode, a limited processing mode, and the like. For implementations that use a fan, the user can select a safe cut-off mode when the temperature of the device reaches a predetermined temperature value.

From the above description, those skilled in the art will now appreciate that the broad teachings of the present invention can be carried out in various forms. Accordingly, although the invention includes specific examples, the scope of the invention should not be so limited.
