  • Page 20: Chapter 1 General Description

    System Configuration This chapter describes the features and configuration of the optical disk drives. The MCE3064SS/MCF3064SS (hereafter optical disk drive) are disks that maintain the compatibility and intend high speed as the succeed drive of the the MCB3064SS/MCC3064SS. The MCE3064SS/MCF3064SS are high-performance, 3.5-inch commutative rewritable optical disk drives which incorporate an SCSI controller.

  • Page 21: Performance

    1-inch height 3.5-inch fixed disk drive form factor. High-speed data transfer • The rpm of the MCE3064SS disk medium is 4558 rpm and MCF3064SS disk medium is 3600 rpm. • The disk drive is capable of 2.94 to 4.9 MB/sec (640 MB) high-speed data transfer.

  • Page 22: Reliability

    Dust resistance Through low power consumption, a cooling fan is rendered unnecessary in the optical disk drive, and through the use of a film on the top and a metal plate on the bottom that excludes dust, a simple, protective sealed construction is realized. This device is compliant with standards for use in a Class 5 millions or lower dust environment.

  • Page 23: Adaptability

    1.1.4 Adaptability Wide operating environment An LSI circuits reduce power consumption to 4.9 W (read/write). This drive features a wide operating environment (drive envronment 5 to 45°C or larger than general office environment). Dust particles are class 5 millions or less. Low noise and low vibration This drive operates quietly (26 dBA or less) even during seek operations and will not degrade the office environment.

  • Page 24

    Mass storage data buffer 2,016 KB buffer is used to transfer data between the SCSI bus and disk. Since data is stored in this buffer, the initiator can execute input-output processing effectively by using the high-speed data transfer capability of the SCSI bus without regard to the data transfer rate of the optical disk drive.

  • Page 26: Configuration

    Therefore, if the spindle motor’s shaft is rotating, the disk medium is rotating at the same speed. A DC brushless motor is used for this spindle motor. It realizes high speed rotation at 4558 rpm for MCE3064SS and 3600 rpm for MCF3064SS, and a high precision rotating system (±0.1%). Actuator section The positioner moves (seeks) a head actuator radially across the disk surface.

  • Page 27: Control Circuit Section Block Diagram

    Separate optical sections The optical head section is separated in such a way that the fixed optics section is separated from the moving optics section to minimize seek time and positioning error. (See Subsection 1.2.4 for the fixed optical section.) This reduces the weight of the moving parts. The fixed optical section consists of the laser diodes, collimator lens, and optical detector.

  • Page 30: Input-output Device Addressing

    1.3.2 Input-output device addressing A unique device address (SCSI ID: #n in Figure 1.5) is assigned to each SCSI device. Input- output devices connected to or under an SCSI device operating as a target are accessed in logical units. A unique device address (LUN: logical unit number) is assigned to each logical unit. An initiator specifies an SCSI ID to select an SCSI device operating as a target, then specifies an LUN to select the input-output device connected to or under the target.

    Implementation of the ARBITRATION phase is a system option. This phase is required for system that has two or more INITs or uses the RESELECTION phase.

  • Page 138: Information Transfer Phases

    If the TARG cannot detect a response from the INIT when the Selection Timeout Delay (recommended: 250 ms) or longer has passed in the RESELECTION phase, the timeout procedure shall be performed though one of the following schemes: 1) The INIT asserts the RST signal to generate the RESET condition. 2) TARG terminates releasing SCSI ID to DATA BUS with maintaining SEL signal and I/O signal in TRUE status.

    Asynchronous transfer In asynchronous transfer mode, information transfer is controlled by the INIT and TARG which are checking the status transition (from false to true and vice versa) of REQ and ACK signals (interlock type). Asynchronous transfer can be used in all types of INFORMATION TRANSFER phase (COMMAND, DATA, STATUS, MESSAGE).

    Data transfer rate in synchronous mode Table 7.8 lists parameters for synchronous data transfer that can be performed by the ODD. Values assigned to these parameters are determined by SYNCHRONOUS DATA TRANSFER REQUEST messages transferred between the INIT and TARG. In a system with more than one INIT, parameters may vary from one INIT to another.

    Note: When the TARG returns a MESSAGE REJECT message to reject an invalid or incorrect message or when the TARG enters a BUS FREE phase as directed by a received message or returns a message (SYNCHRONOUS DATA TRANSFER REQUEST message, for example) in a prompt response to a received message, it can terminate the MESSAGE OUT phase regardless of whether the ATN signal is true or false.

  • Page 152: Switching Direction Of Transfer Over The Data Bus

    • When changing the direction of transfer from Out (from INIT to TARG) to In (from TARG to INIT), the TARG must begin to drive the data bus (DBn) at least 800 ns (Data Release Delay + Bus Settle Delay) after making the I/O signal true. The INIT must stop driving the data bus within 400 ns (Data Release Delay) after the I/O signal becomes true.

    7.5.11 Time monitoring feature The ODD has a time monitoring feature for the SCSI bus to prevent hang-up of the SCSI bus in the case that the TARG cannot receive a response from the INIT in the RESELECTION or INFORMATION TRANSFER phase. Time monitoring in RESELECTION phase The ODD monitors the time of the response (BSY signal) from the INIT in the RESELECTION phase.

  • Page 154: Bus Conditions

    Bus Conditions Two types of asynchronous operations, an ATTENTION condition and a RESET condition, are provided to control and modify the bus phase transition sequence (bus condition). 7.6.1 ATTENTION condition The ATTENTION condition allows an INIT to report that the INIT has messages to be sent to the TARG.

  • Page 155

    Response against ATTENTION condition (TARG) The TARG must enter the MESSAGE OUT phase and respond to the ATTENTION condition under the following situations. After terminating the MESSAGE OUT phase and sending back a MESSAGE REJECT message, the TARG must reenter the MESSAGE OUT phase if the ATN signal is true.

  • Page 156: Attention Condition

    Figure 7.16 ATTENTION condition IMPORTANT The ATTENTION condition generated by the INIT in the SELECTION phase determines the message level to be used in the command execution sequence. (Details are explained in Subsection 2.1.3.) If the ATTENTION condition is not generated in the SELECTION phase, the TARG uses a COMMAND COMPLETE message only.

  • Page 157: Reset Condition

    7.6.2 RESET condition The RESET condition allows all SCSI devices to immediately release the bus. RESET has higher priority than any other phases and bus conditions. Any SCSI device can generate the RESET condition at any time by keeping the RST signal true for 25 µs (Reset Hold Time) or more.
