 Jumper Setting
 ==============

 Drive Configuration - Drive 0/Drive 1 Selection
 -----------------------------------------------

 When the drive is connected to a 68 pin ATA interface, up to two
 drives may be daisy chained on the Host bus. The designation of Drive
 0 or Drive 1 can be made using the Cable Select Option (CSEL).

               CSEL Pin 56

            |                  |-DASP Pin 62      |
            +------------------+------------------+

 By selectively grounding the input signal CSEL the system
 manufacturer can select which drive will recognise itself as Drive 0.
 Linking -DASP (Pin 62) between Drive 0 and 1 will allow Drive 0 to
 recognise that drive 1 is present. -DASP may optionally be connected
 to an activity LED for the Host system.


 LED connection
 --------------
 When a LED is connected on the 68 pin ATA interface (pin 62), an
 external current limiting resistor is required to be placed in series
 between pin 62 and the 5V supply. The value of this resistor is
 dependent on the LED used and is typically 130 Ohms.

 Look Ahead Cache
 ----------------
 The drive has a 32K sector buffer of which, 28K is available to
 buffer data between the disk and host. At the end of each READ
 command, the drive will continue to read data into the sector buffer
 until:-

   1. the sector buffer is full or

   2. a new command other than READ command is received.

 If, during this "look ahead" the drive receives a READ command and
 the requested start block is equal to the start block of the look
 ahead (i.e. continuation of a sequential read) all available blocks
 will be transferred directly from the cache buffer. If more blocks
 are required to complete the transfer the drive will continue to read
 from disk and the read operation will continue. There will be no
 rotational latency incurred. At the end of the command, a new look
 ahead sequence will be initiated.

 If, during this "look ahead" the drive receives a READ command and
 the requested start block is not equal to the start block of the look
 ahead the look ahead will be terminated. The valid blocks currently
 held in cache will then be examined and if the requested start block
 has already been read into the cache then all available data will be
 transferred directly from the cache buffer. If more blocks are re-
 quired to complete the transfer the drive will continue to read from
 disk and the read operation will continue as before else the cache
 pointers will be reset and a new command will be started.

 Introduction
 ------------
 The CT80MC miniature hard disk drive offers a formatted data storage
 capacity of 85.06 Mbytes and is designed to operate on the 68 pin ATA
 and PC CARD-ATA interfaces. The drive is designed with a 10.5mm
 height for compatibility with a PCMCIA Type III card slot. The drive
 and controller electronics use WLSI and surface mount technology to
 allow integration within the 1.8 inch form factor.


 General
 -------
 The CT80MC hard disk drive is a random access data storage device
 which uses two 48mm magnetic disks to provide a formatted capacity
 of 85.06MB. The drive has a fixed physical format of 512 bytes per
 sector, with up to 44 sectors per track.

 --------
 Head/disk assembly (HDA)

 - 3-phase sensorless spindle motor

 - High performance rotary voice coil positioner

 - Fully embedded servo system

 - 50% thin film heads

 - Flex circuit with pre-amplifier and write driver

 - Automatic transit latch

 - Recirculating air filter

 - Breather filter


 Performance

 - Up to 32Kbyte dual ported FIFO buffer with cacheing and look-ahead

 Magnetic Field
 --------------
 There shall be no source of constant magnetic field which results
 more than 0.0005 Tesla measured in the location occupied by the
 magnetic heads when the drive is installed.


 Defect Handling
 ---------------
 A sector skipping technique is used where the logical address of the
 defective sector and all subsequent sectors are advanced by one
 sector. This skipping effect continues until a further defect is
 encountered or the logical end is reached and spare sectors are used
 to complete the specified disk capacity.

 When shipped and after a LOW LEVEL DISK FORMAT has been performed all
 defects will be skipped.

 A number of sectors are reserved for the purpose of mapping out disk
 defects. All disk defects found during manufacturing are stored in a
 Manufacturing Defect List. This list is maintained by the drive and
 store on reserved sectors on the disk.
