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.
