1 Seope

This speeifieation applies to SMD-l00 series (normal power consumption type)

disk drives for 35 flexible dlsks

2 General

SHD-l00 series (normal power eonsumption) drives are flexible disk drives

designed to be used as external memories for personal computers word

processors ete The features of the SHD-100 series drives are described

be 10Yl bull

() Low power consumption SMD-l00 series drives operate on only 2 lW

(wait) and 52W (readwrite) power

(2) Memory medium used i8 35 11 flexible disk encased in a hard cartridge er

equivalent

(3) The disks used have a storage capacity of 500K bytes per aide (equivashy

lent to a eonventional single-sided double-density 525 floppy di sk)

( 4 ) Hi gh t r ack densi ty (1 35 TPI) (S tvt 0 - 1 4 0 1 3 0 )

(5) Use of oe brushless spindle drives assures long trouble-free service

life

(6) The head positioning meehanism employs a step motor and a steel band

enabling fast (3msee) access between tracks (S M 0 - 1 4 0 1 3 0 )

(7) The interface employed is fully compatible with conventional disk qrives

enabling easy replacement

(8) The small aize and light weight (800g) of the SMD-l00 series drives make

thszligm ideally suited to a wide variety of applications

4 Oetailed Specifications

41 Configuration of interface signals

Tha SMD-l00 series (low power consumption) flexible disk drives are

designed so that a maximum of 4 drives can be connected in a daisy chain

configuration All signal input levels are ~TL compatible

The power supply and interface require +SV and +12 V power

411 Electrical specifications of input signals

D~~----------~I~[~ 1438 5 6 KO C-MOa

The terminating resistance array is set at the correct direction

(mark is inside) in the single line socket on the main unit For the

daisy chain connection resistance array can be only installed into

one of the (four) drives

Tbe disk drive with the resistance array instal1ed must be charged

with current in order to operate any of the drives

412 Function of input signals

(1) Drive select 0 3 (080 OS)

A llaxilnum of four S1-10-100 selies (low power consumption) disk drives

can be connected in a daisy chain configuration Selection of the drive

numbers is performed by SSl of the DIe connector on the main PCB When

this switch is operated only the signals from the selected drives will

be input

At the position MX drive is selected no matter ~hat state of

drive select sigIlai

8

(2) Motor ON (MON)

The spindle drive is operated when this signal is low However read and

write operations are only performed when the read (ROY) signal is low

(If the dlsk cartridqe is not set in the drive the spindle drive will

not operate) The RDY signal goe5 low within one second after the MON

signal 15 input when a disk cartridge has been set

(3) Direction (DRTN)

This signal determines the direction of the movement of the step motor

which controls the movement of the readwrite heads When this signal i9

low the readwrite head will move toward the center of the disk and when

it 1s high toward the edge of the dlsk

(4) Step (STP)

The low pulse of this s~gnal causes the middots t e p motor to move in the

direction indicated by the DRTN signal The response step cycle (Ts min)

15 3mstrack for models 140130 and 6mstrack for models 120110 When

the write gate signal 1s low step 1s internally inhibited

Wben the seek direction i5 reversed the reverse step pulse must be sent

after the last pulse (Ts min + 6ettlinq tlwe)

This signal selects between read and write data When th1s signal 1s low

write data 1s enabled and when high read data 1s enabled

Write operations to a cartridge to which a write enable cover has not

be~o affixed are internally inhibited by the disk drive

After the WTO signal goes high there is a 13ms eraae timing For this

reason the see~ or read operation will not begin immediately

(6) Write data (WTO)

This signal transanits the write data that is beiog written to the disk

The fall of th1s signal from high to low causes the ~rite current flowing

through the readwrite head to reverse polarity his signal is operable

only when the write gate signal is low

NOTE This signal is used only ~ith models SMD-lOSMD-120

(8) In use (IUL)

This signal is used to turn the LED on the front panel of the disk drive

on and of f When this signal 1s low the LED turns on and when i t i5

high the LED turns of f bull

This LED is controlled by the drive select signal as the factory-set

condi tion

414 Option functians

By operating the switches on the PeB of the SMD-l00 series diskdrive it is

possible to select the signal that will contral the illumination of the LED

on the front panel of the drive

7 Notes on Use of Drivos

7-1 Powor supply

7-1-1 Two power sources of 12V and SV are required

fhe sequence however is not specified

7-1-2 The rise timo of power supply affects the power on or reset operation of the internal circuit Tharafore tha 90 rise time of thc SV power souree must ba 100015 or less The diskette is protected at power on and power off but the write gate signal should not be allowed to beeome active

7-1-3 When the motor on signal becomas semi-aetive the standby mode is switched on and the operation of the RW circuit is stopped

7-1-4 With a nonnal type the power supply capaeity bocomes maximum at the spindie motor start with 12V system and at the maximum write action with the SV system

7-2 Interface

7-2-1 The signal system is interchangeable with the conventional 525 11 system rhe canne c tor hO-Jever i 5 in compl iance in des i gn lJ i t h S ONY I 5 J 5 d r i v e bull

7-2-2 Daisy chain

Up to tour daisy chain connection is possible The terminating resistancc array is set for all the drivos at the shipment from tho factary Hemove all the arrays on tho samo cablo except far the one on tho end drive

Seleetion for each drivo which is dane by a short plug should be mado carefully without repetition

22

7-2-3 Specification change

The lighting condition of the IN USE LED can be changed by means of a short plug Use it in a desired setting position

7-3 Error ratt

The error rateof the specifications is the value with the fa u 1 t 1 e s s dis le e t t e Well chosen diskettes must be subjected to the error rate test

7 -4 Caution

Tha drive design has taken into consideration the external noise oi CHT etc Bowever do not use it too close to the CRT ~ithout perfect shielding otherwise the Read Write capability of the drive will be doteriorated

7-5 Installation of drive

7-5-1 Install the drive securely usine the four screw holes (M3 PO5 6 DEEP) on the drive side or the four screw holes (M3 ~O5 6 DEEP) on the drive bottom

7-5-2 Sincc the toluumlranc e of the intervals of the instal shylation screw holes i5 ~O2mm ample care must bo exercised in ensurine the positional accuracy and bore accuracy

7-6 Heat generation

Relative positions must be designed with such care that th~ ambient temperature of the drive hecomes the operating temperature of the specifications The upper limit temshyperature must be strictly observed particularly about the diskette
