A motorized sample collection apparatus having a hollow clamshell casing with a contoured grip for the fingers, a horizontal extension to eliminate slippage when held in a user's hand, and a flange bottom portion from which a sample sleeve extends downwards. Within the clamshell casing an electric motor is mounted which drives, via spur gears the sample sleeve in a rotational manner. The distal end of the sample sleeve, is a cutting edge circumscribing a circular region. An ejection rod slides reciprocally within the sample sleeve between a retracted stowed position and an expulsion position. User cuts a sample from a substrate by engaging contact between the cutting edge of the sample sleeve and the substrate, applying pressure against the substrate and activating the motor to rotate the sample sleeve. Activation of the ejection rod towards the expulsion position displaces the sample into an appropriate collecting vessel.

A motorized apparatus to simultaneously excise, retrieve, temporarily store and transport a sample of material has a hollow clamshell casing with a blended contoured grip for the fingers, a horizontal extension to eliminate slippage when held in a user's hand, and a flange bottom portion from which a removable cutting tool threaded to a drive shaft extends downwards. Within the clamshell casing an electric motor is mounted which drives, via gears, a drive shaft which rotates a cutting tool threaded to the distal end of the drive shaft. The end of the cutting tool, distal from the clamshell casing, forms a cutting edge circumscribing a circular region. An ejection rod slides reciprocally within the cutting tool between a stowed position and an expulsion position. Users core a sample from the source material by engaging contact between the cutting edge of the cutting tool and the surface of the source material, applying pressure against the surface of the source material while simultaneously activating the motor to rotate the cutting tool. The cutting region of the cutting tool passes through the source material contacting the support surface below the source material which urges the cored sample into the lumen of the cutting tool. The sample may be stored in the lumen or transported. Activation of the ejection rod moves from the stowed position towards the expulsion position displacing the temporarily stored sample from the lumen space in the cutting tool into the appropriate collection receptacle or onto a desired surface.

Embodiments of the invention provide an inexpensive magnetic head tester employing component parts of a production HDD and capable of exercising functions very close to those of a production HDD. In one embodiment, a magnetic head tester employs the VCM actuator and the control circuit of a production HDD and has a lightweight, simple HGA fixing mechanism mounted on an actuator arm. The HGA fixing mechanism fixes an HGA to the actuator arm by a method using a very light holding spring mounted on the arm, a method of mechanically clamping an HGA by using air pressure, or a method of fixing an HGA to the arm by elastically deforming a rubber clamping member by air pressure. Servo control is achieved by the actuator of a production VCM. An end part of the VCM actuator is stopped by a stopping mechanism and is held by a holding spring to prevent the runaway of the VCM actuator. Servo control is performed by balancing the driving force of the VCM and the resilience of the spring.
