Abstract

A system, method, and apparatus for coordinating tasks in a control system for an optical disc drive for optical media with a pitted premastered area that cannot be overwritten and a grooved user-writable area that can be overwritten. The optical disc drive includes a first processor operable to communicate with a second processor, wherein the first processor includes instructions for performing non-time-critical tasks, and the second processor includes instructions for performing time-critical tasks, such as reading from and writing to optical media in the disc drive. The first processor monitors the status of the time critical tasks in the second processor and transmits commands to perform operations in the second processor. The first processor also controls power mode, manages recovery from errors, controls focus, tracking/seeking, spin, physical sector address (PSA), a laser, adjusts gains, and monitor cartridge load/eject. The first processor sequences and monitors functions performed in the second processor and the second processor issues an interrupt when an error condition is detected in the second processor. The first processor detects the interrupt, and disables detecting further interrupts until the interrupt is serviced. Servicing the interrupt includes recording the error state and changing focus and tracking parameters based on the error condition detected. The first processor can be used to perform other tasks while it is waiting to receive a notice of a new command, a notify event, or a performance event.

In some embodiments, the request for notification of the event is issued by the power interruption 408 and the email mailbox interruption 306 when a problem or error is detected. The real-time operating system (RTOS) 406 then sends the notification event to the servo thread 404. In some embodiments, a program 704 monitors the time between these notification events and the number of this notification events to avoid excessive responses. The parameters used to determine when a reply will become excessive can be set based on several different conditions, such as the number of reply attempts during a predetermined time. For example, in some embodiments, five reply attempts within five seconds may be judged as exceeding, and other parameters and values may be applied in other embodiments. If the reply does not exceed, a program 706 will stop the reply state machine in the power interruption 408 by transferring the delay, thereby starting a reply to the notification event.

Initialize this track to get status machine 1 300. If the start reading head is loaded with the machine 1 3 6 2 to detect that the focus servo loop is not closed, or the tracking loop is closed, then this state transitions to 1 this track closed state 1 322, where The programmer who turned off tracking was initiated. In this initial read head loading state 1 362, if the focus servo system is closed and the tracking servo system is open, a bias voltage is applied to the tracking actuator and depends on the optical disc drive 00. The position of an internal diameter (ID) collision resistance. The loading state of the start reading head 丨 362 also sets the rotation speed to a predetermined speed, such as 293 ° RpM, and programs the digital processor (DSP) 3 0 4 to sample and report the track error Signal (TES). Then ‘this read head loading state 1 3 6 2 is switched to a h e a d 1 〇 a d 1 state 1 3 6 6.

The headload1 state 1 366 is delayed by a predetermined time period, such as: 30 milliseconds, to allow the settling time for the tracking gear to crash against the inner diameter (ID), and to give the digital signal processor (DSP) 3 04 Time to complete the first measurement. Subsequently, this state transitions to a headload2 state 1 368, where it collects more orbit errors, k number (TES) samples. When a completely predetermined number of samples are collected, this state transitions to a headload3 state 1 370, where the orbital error signal (TES) sampling is used to determine whether the optical bench unit (ΟΡϋ) 103 is located including the road Above this part of the optical media 102. If the optical acquisition unit (〇ρυ)] 03 is located above the orbital portion, the orbital error signal (TES) has a sine wave shape and many sampling points will be far away from the average value of the sine wave and closer to the peak.

When deviating from the orbital portion of the optical capture unit (〇PU) i 〇3, the execution error signal (TES) is not a sine wave and is approximately centered around an average value, except that the Outside the special position. Therefore, if the optical pickup unit (0PlJ) 103 is not located above the orbital portion, most of the sampling points will be fairly close to the average of the collected orbital error signal (TES). The difference in the distribution of these track error signal (TES) samples is used in the headi0ad3 state 1 370 'to determine whether the optical capture unit (〇ρ〇) ι03 is located above the optical medium 102. If the headl0ad3 state 1 370 determines that the optical capture unit (〇PU) 1 〇3 is not located above the optical medium 102, then the tracking bias system is reduced, thereby reducing the tracking drive Push toward the inner diameter (D) of the collision blocking force and perform a transition back to the headloadl state 1 362. This procedure with these states 1 3 6 6, 1 368, 1 370 is repeated 'until this state 1 370 determines that the optical pickup unit (0PU) 1 03 is indeed located above the orbital part, or until the forcing The biasing force of the tracking transmission device pushing toward the inner diameter (D) collision stop is reduced to pass a predetermined point, which determines that the loading state of the read head mechanism 1390 has failed. If the read head is loaded in the state machine, the 3-9 ° system fails, a conversion system is executed to change from this state 1 370 to the track closed state 1322 ° If the headi 0ad3 state 1 370 system determines the optical pick-up order疋 (0PU) 1 〇3 is already located above this track part, then the tracking bias is further increased, in this embodiment it is ox200 count, and this state is switched to a headload4 state 1 37 2.
