SCOPE

The Tandon Magnetics Corporation Flexible Disk Drive is a compact Data Storage device utilizing an Industry Standard 5.25 inch Diskette (133.4mm).

The Aexible Disk Drive provides double density capability when a Modified Frequency Modulated (MFM) or other appropriate Recording Technique is utilized. The encoding and decoding of the data is the user's responsibility.

, WRITE PROTECT (STANDARD)

When a Write Protected Diskette is inserted in the Flexible Disk Drive, the Write Electronics are disabled.

BUSY INDICATOR (STANDARD)

A Busy Indicator located on the Front Panel will become illuminated when the Flexibie Disk Drive is selected.

DAISY CHAIN CAPABILITY (STANDARD) •

The unit provides Address Selection and gating Functions necessary to Daisy-chain a maximum of four (4) Drives at the user's option. The last unit on the Daisy Chain terminates the Interface. The terminations are accomplished by a resistor array plugged into a D.LP. Socket.

INTERNAL TRIM ERASE (STANDARD)

.' The flexible Disk Drive provides internally the necessary control signal for proper Trim e~asure of Data.

INTERFACE

The I/O is an Industry Compatable Interface. The Connector is a 34 pin edge card connector (PI).

The mating COflllt.dor (PI not supplied) may be a Scotch-Flex Ribbon connecting, 3M PN-3463-00I or alternatively an

AM

PN-5837I7-5 utilizing contacts PN-I-5836I6-1 for Twisted pair. Signal Connector pin assignments can be found in Table 2.

INPUT CONTROL LINES DRIVE SELECT LINES

The DRIVE SELECT lines provide a means of selecting and deselecting a disk drive. These four lines select one of the four disk drives attached to the controller.

When the signal logic level is true (low), the disk drive ele.ctronics are activated, the head is loaded and the drive is conditioned to respond to Step or Read/Write commands. When the signal line logic level is false (high), the input control lines and output status lines are disabled.

A DRIVE SELECT line must remain stable in the true (low) state until the execution of a Step or Read/Write command is completed.

The disk drive address is determined by a Select Shunt on the signal PCBA. DRIVE SELECT lines

o

through 3 provide a means of daisy-chaining a maximum of four disk drives to a controller. Only one line can be true (low) at a time. An undefined operation might result if two or more units are aSSigned the same address or if two or more DRIVE SELECT lines are in the true (low) state simultaneously.

MOTOR ON

When this signal line logic level goes true (low), the drive motor accelerates to its nominal speed of 300 RPM and stabilizes at this speed in less than 250 milliseconds. When the signal line logic level goes false (high), the disk drive decelerates to a stop in less than 150 milliseconds. This signal is not gated with select.

DIRECT SELECT and STEP Lines (2 Lines)

When the disk drive is selected, a true (low) pulse with a time duration greater than 1 usec, but less than 2 msec, on the STEP line initiates the access motion. The direction of motion is determined by the logic state of the DIRECTION SELECT line when a STEP pulse is issued. The motion is towards the center of the disk if the DIRECTION SELECT line is in the true (low) state when a STEP pulse is issued. The direction of motion is away from the <:enter of the disk if the DIRECTION SELECT line is in the false (high) state when a STEP pulse is issued. To ensure proper positioning, the DIRECTION SELECT line should be stable 1 usec (minimum), prior to issuing a corresponding STEP pulse and remain true (low) until I usec after the STEP pulse. The access motion is initiated on the trailing edge of the STEP pulse.

The time period between consecutive trailing edges of STEP pulses should not be less than 5 msec.

The Drive Electronics will ignore STEP pulses when either of the following conditions exist:

(A) The WRITE ENABLE is true (low)

(B) The direction SELECT is false (high) and the HEAD is position at track

00

(C) The DRIVE is not selected COMPOSITE WRITE DATA

When the disk drive is selected, this interface line provides the bit-serial COMPOSITE WRITE DATA pulses that control the switching of the write current in the selected head. The write electronics must be conditioned for=writing by the WRITE ENABLE line (see Para. 5.4.1.6).

For each high-to-Iow transition on the COMPOSITE WRITE DATA line, a flux change is produced at the write head gap. This will cause a flux change to be stored on the medium.

When a double-frequency type encoding technique is used in which data and clock form the combined Write Data signal, the following is recommended.

(1) (2)

The repetition of the high-to-Iow transitions, when writing all zeros, should be equal to the nominal data rate,

±

0.1

(~~

\::: B/5

The repetition rate of the high-to-Iow transitions, when writing all ones, should be equal9to

twice the nominal data rate,

±

O;}

%; .

WRITE ENABLE

When this signal is true (low), the write electro'nics are prepared for writing data (the read electronics are disabled). This signal turns on write current in the selected Read/Write head. Data is written under the control of the COMPOSITE WRITE DATA and SIDE ONE SELECT input lines. It is generally recommended that changes of state on the WRITE ENABLE line occur before the first WRITE DATA pulse. When the WRITE ENABLE line is false (high), all write electronics are disabled.

When a write-protected diskette is installed in a drive, the write electronics are disabled irrespective of the state of the WRITE ENABLE of SIDE ONE SELECT lines.

OUTPUT STATUS LINES INDEX/SECTOR

The INDEX/SECTOR signal is a composite of the Index pulse and Sector signals.

An Index pulse is provided once every revolution (200 msec, nominal) to indicate to the controller the beginning of a track. The leading edge of this signal must always be used to insure timing accuracy.

The INDEX/SECTOR line remains in the true (Jow) state for the duration of the INDEX/SECTOR pulse. The duration of the INDEX/SECTOR pulse is nominally 3.5 msec.

The Sector signal portion appears only when using hard-sectored diskettes.

TRACK 0

When the disk drive is selected, the TRACK 0 interface signal indicates to the controller that the Read/Write head is positioned on TRACK

O.

The TRACK 0 signal remains true (low) until the head is moved away from TRACK 0_

WRITE PROTECTED

The NWPTD signal line level goes true (low) when the diskette is write protected, the write electronics are internally disabled!

With WRITE PROTECTED false (high), the write electronics are enabled and Write operations can be performed_ It is generally recommended that the controller should not issue a Write command when the WRITE PROTECTED signal is true (low).

COMPOSITE READ DATA

This interface line transmits the readback data to the controller when the drive is selected. It provides a pulse for each flux transition recorded and detected on the diskette. The COMPOSITE READ DATA output line goes true (low) for a duration of 1

:!:

.25 usec for each flux change recorded on diskette.

The leading edge of the COMPOSITE READ DATA output pulse represents the true positions of the flux transitions on the diskette surface.
