TAPE ADJUSTMENTS

a. Replacing the head

1. After replacement, demagnetize the heads by using
a degausser.

2. Be sure to clean the heads before attempting to make
any adjustments.

3. Be sure both channels (1 and 2) are the same level.
(Using a dual-channels oscilloscope).

4. All wiring should be returned to the original position
after work is completed.

c. Adjusting motor speed

1. Insert the test tape (MTT-111 or etc. 3,000 Hz).

2. Press the PLAY button.

3. Use a flat-tip screwdriver to turn the SVR to adjust so
that the frequency counter becomes 3,000 Hz.

4. Press the STOP button.

b. Adjusting head azimuth

1. Load a test tape (VTT-738, etc. :10kHz) for
azimuth adjustment.

2. Press the PLAY button.

3. Use a cross-tip screwdriver to turn the screw for
normal azimuth adjustment so that the left and right
outputs are maximized at the same phase during
normal playback.

4. Press the STOP button.

e. Checking the mechanism torques

• Clean the head, capstan and pinch roller before making
any measurement.

Active on the positive going edge to sample all inputs.
Disables or enables device operation by masking or enabling all inputs except CLK,CKE
and L(U)DQM.
Makes system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disable input buffers for power down in standby.
Row / column addresses are multiplexed on the same pins.
Row address : RA0~RA10, column address : CA0~CA7
Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.
Latches row addresses on the positive going edge of the CLK with RAS low.
Enables row access & precharge.
Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.
Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
Makes data output Hi-Z tSHZ after the clock and masks the output.
Blocks data input when L(U)DQM active.
