Page 64: Self-Calibration
Theory of Device Operation 4.5 Self-calibration The disk drive occasionally performs self-calibration in order to sense and calibrate mechanical external forces on the actuator, and VCM torque. This enables precise seek and read/write operations. 4.5.1 Self-calibration contents (1) Sensing and compensating for external forces The actuator suffers from torque due to the FPC forces and winds accompanying disk revolution.
Page 65: Execution Timing Of Self-Calibration
To compensate torque constant value change depending on cylinder, whole cylinders from most inner to most outer cylinder are divided into 13 partitions at calibration in the factory, and the compensation data is measured for representative cylinder of each partition. This measured value is stored in the SA area.
Page 66: Read/Write Circuit
Theory of Device Operation 4.6 Read/write Circuit The read/write circuit consists of the read/write preamplifier (PreAMP), the write circuit, the read circuit, and the time base generator in the read channel (RDC) block which is integrated into LSI. Figure 4.4 is a block diagram of the read/write circuit.
Page 67: Read Circuit
4.6.3 Read circuit The head read signal from the PreAMP is regulated by the automatic gain control (AGC) circuit. Then the output is converted into the sampled read data pulse by the programmable filter circuit and the flash digitizer circuit. This signal is converted into the read data by the decoder circuit based on the read data maximum-likelihood-detected by the Viterbi detection circuit.
Page 68: Servo Control
Theory of Device Operation 4.7 Servo Control The actuator motor and the spindle motor are submitted to servo control. The actuator motor is controlled for moving and positioning the head to the track containing the desired data. To turn the disk at a constant velocity, the actuator motor is controlled according to the servo data that is written on the data side beforehand.
Page 69 (1) Microprocessor unit (MPU) The MPU executes startup of the spindle motor, movement to the reference cylinder, seek to the specified cylinder, and calibration operations. The main internal operations of the MPU are shown below. Spindle motor start Starts the spindle motor and accelerates it to normal speed when power is applied.
Page 70: Data-Surface Servo Format
Theory of Device Operation (6) Driver circuit The driver circuit is a power amplitude circuit that receives signals from the spindle motor control circuit and feeds currents to the spindle motor. (7) VCM current sense resistor (CSR) This resistor controls current at the power amplifier by converting the VCM current into voltage and feeding back.

Theory of Device Operation 4.7.3 Servo frame format As the servo information, the IDD uses the phase signal servo generated from the gray code and servo EVEN and ODD. This servo information is used for positioning operation of radius direction and position detection of circumstance direction.
Page 73: Actuator Motor Control
4.7.4 Actuator motor control The voice coil motor (VCM) is controlled by feeding back the servo data recorded on the data surface. The MPU fetches the position sense data on the servo frame at a constant interval of sampling time, executes calculation, and updates the VCM drive current.
Page 74: Spindle Motor Control
Hall-less three-phase twelve-pole motor is used for the spindle motor, and the PWM type current control circuit is used as the spindle motor driver (called SVC hereafter). The firmware operates on the MPU manufactured by Fujitsu. The spindle motor is controlled by sending several signals including the serial data from the MPU to the SVC.

Page 266: Response To Comreset
Operations 6.1.2 Response to COMRESET The response to COMRESET is almost the same as the response when power is turned on and a power-on reset is then cancelled. The device establishes communication with the SATA interface (PHY Ready) and sends the RegDH FIS (STS = 50h) to notify the host that the device is ready.
Page 267 6.1.2.1 Software settings preservation When a device is enumerated, software will configure the device using SET FEATURES and other commands. These software settings are often preserved across software reset but not necessarily across hardware reset. In Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are cleared for the particular type of reset it has issued.

6.1.3 Response to a software reset When a software reset is accepted, the device performs a self-diagnosis, and it sends the RegDH FIS (STS = 50h) to notify the host that the device is ready. Then, the software reset sequence is completed. Figure 6.4 Response to a software reset C141-E280 6.1 Reset and Diagnosis...
Page 270: Power Save
Operations 6.2 Power Save The host can change the power consumption state of the device by issuing a power command to the device. 6.2.1 Power save mode There are five types of power consumption state of the device including active mode where all circuits are active.
Page 271 • Upon receipt of a COMRESET • Upon receipt of Idle/Idle Intermediate (4) Standby mode In this mode, the spindle motor has stopped from the low power idle state. The device can receive commands through the interface. However if a command with disk access is issued, response time to the command under the standby mode takes longer than the active, active idle, or low power idle mode because the access to the disk medium cannot be made immediately.
Page 272: Power Commands

Page 274 Operations (3) Slumber mode In this mode, the (deep) Power Save mode is set for the interface circuit. The device switches to Slumber mode when the following occurs: • The device receives the PMREQ_P signal from the host and responds with the PMACK signal.
Page 275: Read-Ahead Cache
6.4 Read-ahead Cache Read-ahead Cache is the function for automatically reading data blocks upon completion of the read command in order to read data from disk media and save data block on a data buffer. If a subsequent command requests reading of the read-ahead data, data on the data buffer can be transferred without accessing the disk media.
Page 276: Caching Operation
Operations 6.4.2 Caching operation The caching operation is performed only when the commands listed below are received. If any of the following data are stored on the data buffer, the data is sent to the host system. • All of the sector data that this command processes. •...
Page 277 (3) Invalidating caching-target data Data that is a target of caching on the data buffer is invalidated under the following conditions: 1)-1 Any command other than the following commands is issued. (All caching- target data is invalidated.) READ BUFFER WRITE BUFFER RECALIBRATE FORMAT TRACK SET FEATURES...
Page 278: Using The Read Segment Buffer
Operations 6.4.3 Using the read segment buffer Methods of using the read segment buffer are explained for following situations. 6.4.3.1 Miss-hit In this situations, the top block of read requested data is not stored at all in the data buffer. As a result, all of the read requested data is read from disk media. 1) HAP (host address pointer) and DAP (disk address pointer) are defined in the head of the segment allocated from Buffer.
Page 279 6.4.3.2 Sequential hit When the read command that is targeted at a sequential address is received after execution of the read commands is completed, the read command transmits the Read requested data to the host system continuing read-ahead without newly allocating the buffer for read.
Page 280 Operations 6.4.3.3 Full hit In this situation, all read requested data is stored in the data buffer. Transfer of the read requested data is started from the location where hit data is stored. For data that is a target of caching and remains before a full hit, the data is retained when execution of the command is completed.
Page 281 6.4.3.4 Partial hit In this situation, a part of read requested data including the top sector is stored in the data buffer. A transfer of the read requested data starts from the address where the data that is hit is stored until the top sector of the read requested data. Remaining part of insufficient data is read then.
Page 282: Write Cache
Operations 6.5 Write Cache Write Cache is the function for reducing the command processing time by separating command control to disk media from write control to disk media. When Write Cache is permitted, the write command can be keep receiving as long as the space available for data transfers remains free on the data buffer.
Page 283 (3) Status report in the event of an error The status report concerning an error occurring during writing onto media is created when the next command is issued. Where the command reporting the error status is not executed, only the error status is reported. Only the status of an error that occurs during write processing is reported.
