	*1	During random seek or read/write but excluding pulse waveform at 500 ∝ s
		or less

*2 Average value at an ambient temperature of 25°C and a voltage of 5 V

*3 The performance is specified at an ambient temperature of 25°C and level placement at 0°.

Note:

1.The current limiter value on the power supply must not exceed 5 A.

2.The specifications for during transport are under the packaging conditions specified by Fujitsu.

3.Note that, concerning the power requirements, a voltage drop may occur depending on the power cable in use.

2.1.4Error rate

Data blocks to be accessed should be evenly distributed on the disk. Errors due to disk defects are not included.

(1) Bit error rate after ECC processing

The error rate after ECC processing must be 10-12or less. An optical disk whose raw error rate is 10-4or less should be used.

(2) Positioning error rate

The positioning error rate must be 10-6or less (with retry).
