A miniature magnetic disk device or a miniature optical disk device has a recording disk having a diameter less than or equal to 0.7 inches. The disk device also includes a spindle motor which rotates the recording disk, a read/write head for recording or reproducing information on and from the recording disk, a support member which holds the read/write head, and a support shaft which is coupled to the support member. A voice coil motor, which is coupled to the support member and the support shaft, sets the read/write head in a desired position over the disk. A resistor which has a value of at least 2.5 OMEGA is connected in series with a coil of the voice coil motor, and the resistor makes it possible to reduce power consumption of the voice coil motor. The resistor may be a variable resistor, and a conductor of the coil may have a cross-sectional area less than 2.55x10-3 mm2. A ratio h/t of a thickness h of the coil to a thickness t of a magnetic circuit of the voice coil motor have be at least 0.25. Moreover, by mounting several of these disks on a board which is standardized as PCMCIA type 3, a miniature array disk device is formed.
