The HHB 3.5" 640MB Magneto Optical disks were developed specifically for professional audio use. HHB recognized the increased adoption of the 3.5" MO format for professional audio use, as evidenced by the Yamaha D24 24-bit digital audio recorder.
The HHB MO 640MB disks are extensively tested for performance and compatibility in a wide range of recorders and both conform to ISO/IEC 15041CD standards.
The HHB 3.5" MO disks employ a precision sputtered MO thin film on a polycarbonate substrate to ensure consistently low block error rates, a high carrier to noise ratio and more than 1 million rewrite cycles. An anti-static hard coating repels dust from the disk surface, helping to deliver a secure archival life in excess of 30 years.
HHB's long experience as an MO media manufacturer has gained the company a unique insight into the MO format.
There is a high Demand for MO media with an increasing number of users considering it to be the most dependable format available. The large capacity and fast access times makes it ideal for hi-bit / hi-sampling recording, so MO is regularly used on high profile projects, where demand for the performance and dependability of HHB media is all the more acute.
