DESCRIPTION AdvintelligentTape5 Density support data blocks will be returned by ascending primary density code values Primary Density Code This field contains the value returned by a Mode Sense command for the density described in the remainder of the density support block The drive will accept a Mode Select command containing this value for appropriate media The value of 00h will only be used for the default of the logical unit WRTOK The WRTOK bit of ZERO indicates that logical unit support for this density does not include writing to the media The WRTOK bit of ONE indicates the logical unit is capable of writing this density to either the currently mounted medium Media bit in CDB set to one or for some media Media bit in CDB set to Zero DUP The DUP bit of ZERO indicates this primary density code has exactly support data block The DUP bit of ONE indicates this primary density code is specified in more than one density support block DEFLT The DEFLT bit of ZERO indicates this density is not the default density of the drive The DEFLT of ONE indicates this density is the default density of the logical unit Bits Per MM This field indicates the number of bits per millimeter per track as recorded on the medium The value in this field will be rounded up if the fractional value of the actual value is greater than or equal to 0 5 A value of 00h indicates that the number of bits per millimeter does not apply to this logical unit
16. Direct of this value between different suppliers possible products is discouraged since the definition of bits may vary Media Width This field indicates the width of the medium supported by this density This field has units of tenths of millimeters The value in this field is equal to 0 5 The Media Width field may vary for a given density depending on the mounted medium A value of 00h indicates that the width of the medium does not apply to this logical unit Tracks This field indicates the number of data tracks supported on medium by this density Capacity If MEDIA bit of CDB is set to 0 this field will indicate the approximate capacity of the longest supported medium assuming recording in this density If the Media bit of CDB is set to 0 set to Om this field will indicate the approximate capacity of the current medium assuming recording in this density If the approximate capacity of the current medium cannot be determined for the mounted medium the longest supported medium capacity will be used The data and block size assumes that compression is disabled The capacity also assumes that the media is in good condition and that normal data and block size are used This value is in units of megabytes 1000 X 1000 bytes The logical unit does not guarantee that this space is actually available in all cases SONY AIT 5 drive SDX 1100V series Ver 1 0 6 81 6 Command Specification REPORT DEVICE IDENTIFIER 6 20 REPORT DEVICE ID
