■ Background of Development

Non-tape media camcorders such as DVD and HDD camcorders have grown to dominate more than
80% of the camcorder market
consumer camcorder market

Hitachi, with its corporate statement “Inspire the Next, ” has been creating new product categories and
established new standards in the industry. In 2000, Hitachi introduced the world’s first DVD camcorder,
and in 2006, the world’s first hybrid camcorder with a DVD drive and an HDD drive, which makes it easy
to dub the contents on the HDD to the DVD. The spirit behind the innovation was always a careful
consideration of the customer’s needs.

(*3). High definition camcorders have taken more than 30% of the

(*3), and are expected to continue growing.

This time, with the keyword “A True Breakthrough in Your Hand,” Hitachi developed an 8cm BD/DVD
Drive for Camcorders, Full High Definition Signal Processor Engine “Picture Master Full HD”, and CM OS
Image Sensor for Full High Definition

(*2). With these core technologies, Hitachi adopted BD as a media

since it has more than five times the capacity of a DVD and can record 1 hour of 1920x1080 full high
definition video on one disc to create two models of the world’s first BD camcorders, which shoot,
playback, and store full high-definition in every process. Hitachi will continue to mobilize its technology
to introduce camcorders that meet the needs of the consumers.

■ Main Features for Keeping Fresh and Vivid Memories – 1920x1080 Full High Definition

throughout Imaging, Recording, and Playback

1. World’s First

(*1) 8cm BD/DVD Drive (plus 30GB HDD for Hybrid model)

(1) Hitachi Original 8cm BD/DVD Drive

Hitachi developed a compact, low power consuming, and reliable 8cm BD/DVD drive
which corresponds to five kinds of 8cm discs; BD-RE/-R, DVD-RAM/-RW/-R.

*1: BD camcorder BD/DVD drive does not comply with dual layer discs.

(*1)

1) The drive carries two optical pick-ups for BD and DVD and a flat pick-up with

compact aberration correction function for BD. The size of the drive chassis

8cm BD/DVD Drive

remains almost the same as the DVD camcorder drive.

2) The drive can record and playback full high definition. BD has approximately five times the

capacity and approximately three times the rapid transfer rate compared with DVD.

3) Low power consumption by intermittent recording technology which is the combination of rapid

recording on the disc and memory buffer function.

4) P-CAV (Partial-Constant Angular Velocity) Control Technology has been

developed for rapid disc rotation speed essential for full high definition
recording and also to maintain silence.

(2) 8cm BD Recording

The camcorder can record record one hour of 1920x1080 pixels full high-definition video on a 8cm BD
(single side, single layer 7.5GB) which is a convenient media to stock. BD-RE discs are re-writable,
whereas BD-R discs can record once.

(3) Large Capacity 30GB HDD (DZ-BD7H)

1) “30GB HDD” can record long hours without caring about the remaining time

on the media. 30GB HDD can record up to four hours of 1920x1080 pixels
full high definition video (HX mode), or eight hours of 1440x1080 pixels high
definition video (HS mode).

2) “Impact Resistant Damper” protects the HDD from shock and moderates

impact to 50%.

30GB HDD

3) “Head Load/Unload Structure” removes head away from the disc when not

in operation in order to prevent the head from touching the disc when impact is
given to the HDD.

2. High Picture Quality Video Engineering for Shooting 1920x1080 Pixels Full High Definition

(1) Full High Definition Distortion-less Lens

10x zoom non-spherical lens has been developed to maintain compact body size. It
captures 2400x1800 pixels still photo as well as 1920x1080 full high-definition video.
The lens is multi-coated to prevent reflection, flare, or ghost images, and has
gradation ND (neutral density) filter to prevent degrading of resolution caused by
aperture of iris.

Full HD Lens

(2) CMOS Image Sensor for Full High Definition Video and Approximately 4.32

Mega Pixel Still Photo

Approximately 5.3 mega pixel CMOS Image Sensor co-developed with AltaSens, Inc.
captures the true nature of the object in progressive format and has RGB primary
color filter. CMOS image sensor is ca pable of reading pixel area randomly at a rapid
speed essential for full high definition video imaging. (1920x 1080) It can capture
still photo image at 2400x1800 pixels. Pixel size of the CMOS image sensor is

2.09µm, 1/2.8 inches in size, and total pixel size of approximately 5.3 mega pixel has

electronic image stabilization function with is controlled outside the range of effective
pixels.
