23. Theory of Device Operation 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 The servo control of the actuator includes the operation to move the head to the reference cylinder the seek operation to move the head to the target cylinder to read or write data and the track following operation to position the head onto the target track 1 Operation to move the head to the reference cylinder The MPU moves the head to the reference cylinder when the power is turned The reference cylinder is in the data area When power is applied the heads are moved from the outside of media to the normal servo data zone in the following sequence a Micro current is fed to the VCM to press the head against the outer direction b The head is loaded on the disk c When the servo mark is detected the head is moved slowly toward the inner circumference at a constant speed d Ifthe head is stopped at the reference cylinder from there Track following control starts 2 Seek operation Upon a data read write request from the host the MPU confirms the necessity of access to the disk If a read write instruction is issued the MPU seeks the desired track The MPU feeds the VCM current via the D A converter and

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 In Serial ATA COMRESET is equivalent to hard reset and a non commanded COMRESET may occur if there is an asynchronous loss of signal Since COMRESET is equivalent to hardware reset in the case of an asynchronous loss of signal some software settings may be lost without legacy software knowledge In order to avoid losing important software settings without legacy driver knowledge the software settings reservation ensures that the value of important software settings is maintained across a COMRESET Software settings preservation may be enabled or disabled using SET FEATURES with a subcommand code of 06h refer to Section 5 3 2 28 If a device supports software settings preservation the feature shall be enabled by default 6 1 2 2 COMRESET preservation requirements The software settings that shall be preserved across COMRESET are listed below The device is only required to preserve the indicated software setting if it supports the particular feature command the setting is associated with e INITIALIZE DEVICE PARAMETERS Device settings
