Travelstar 80GN Hard Disk Drive Specification
36
Tt = published seek time from one random track to another without including rotational latency
T1= equivalent time in seconds for the drive to rotate by half a revolution
6.6.2
Discrete tone penalty
Discrete tone penalties are added to the A-weighted sound power (Lw) with the following formula only when
determining compliance.
Lwt(spec) = Lw = 0.1Pt + 0.3 < 4.0 (Bels)
where
Lw = A-weighted sound power level
Pt = Value of desecrate tone penalty = dLt – 6.0(dBA)
dLt = Tone-to-noise ratio taken in accordance with ISO 7779 at each octave band
6.7
Identification labels
The following labels are affixed to every drive:
A label which is placed on the top of the head disk assembly containing the statement "Made by Hitachi" or
equivalent, part number, EC number, and FRU number.
A bar code label which is placed on the disk drive based on user request. The location on the disk drive is to
be designated in the drawing provided by the user.
Labels containing the vendor's name, disk drive model number, serial number, place of manufacture, and UL/
CSA logos.
Labels containing jumper information if required by the customer.
6.8
Electromagnetic compatibility
When installed in a suitable enclosure and exercised with a random accessing routine at maximum data rate meets
the worldwide EMC requirements listed below:
United States Federal Communications Commission (FCC) Rules and Regulations (Class B), Part 15
RFI Japan VCCI, Requirements of IBM products
EU EMC Directive, Technical Requirements and Conformity Assessment Procedures
6.8.1
CE mark
The product is certified for compliance with EC directive 89/336/EEC. The EC marking for the certification
appears on the drive.
6.8.2
C-TICK mark
The drive complies with the Australian EMC standard "Limits and methods of measurement of radio disturbance
characteristics of information technology equipment, AS/NZS 3548:1995 Class B."
6.8.3
BSMI mark
The product complies with the Taiwan EMC standard"Limits and methods of measurement of radio disturbance
characteristics of information technology equipment, CNS 13438 Class B."
